Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in Wolff-Parkinson-White syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel.

Clinical application of an integrated 3-phase mapping technique for localization of the site of origin of idiopathic ventricular tachycardia. (1/507)

BACKGROUND: Radiofrequency (RF) catheter ablation provides curative treatment for idiopathic ventricular tachycardia (VT). METHODS AND RESULTS: Nineteen consecutive patients with an idiopathic VT underwent RF catheter ablation. An integrated 3-phase mapping approach was used, consisting of the successive application of online 62-lead body surface QRS integral mapping, directed regional paced body surface QRS integral mapping, and local activation sequence mapping. Mapping phase 1 was localization of the segment of VT origin by comparing the VT QRS integral map with a database of mean paced QRS integral maps. Mapping phase 2 was body surface pace mapping during sinus rhythm in the segment localized in phase 1 until the site at which the paced QRS integral map matched the VT QRS integral map was identified (ie, VT exit site). Mapping phase 3 was local activation sequence mapping at the circumscribed area identified in phase 2 to identify the site with the earliest local endocardial activation (ie, site of VT origin). This site became the ablation target. Ten VTs were ablated in the right ventricular outflow tract, 2 at the basal LV septum, and 7 at the midapical posterior left ventricle. A high long-term ablation success (mean follow-up duration, 14+/-9 months) was achieved in 17 of the 19 patients (89%) with a low number of RF pulses (mean, 3.3+/-2.2 pulses per patient). CONCLUSIONS: This prospective study shows that integrated 3-phase mapping for localization of the site of origin of idiopathic VT offers efficient and accurate localization of the target site for RF catheter ablation.  (+info)

Ventricular excitation maps using tissue Doppler acceleration imaging: potential clinical application. (2/507)

OBJECTIVES: The purpose of this study is to validate the use of tissue Doppler acceleration imaging (TDAI) for evaluation of the onset of ventricular contraction in humans. BACKGROUND: Tissue Doppler acceleration imaging can display the distribution, direction and value of ventricular acceleration responses to myocardial contraction and electrical excitation. METHODS: Twenty normal volunteers underwent TDAI testing to determine the normal onset of ventricular acceleration. Two patients with paroxysmal supraventricular tachycardia and 30 patients with permanent pacemakers underwent introduction of esophageal and right ventricular pacing electrodes, respectively, and were studied to visualize the onset of pacer-induced ventricular acceleration. Eight patients with dual atrioventricular (AV) node and 20 patients with Wolff-Parkinson-White (WPW) syndrome underwent TDAI testing to localize the abnormal onset of ventricular acceleration, and the results were compared with those of intracardiac electrophysiology (ICEP) tests. RESULTS: The normal onset and the onset of dual AV node were localized at the upper interventricular septum (IVS) under the right coronary cusp within 25 ms before the beginning of the R wave in the electrocardiogram (ECG). In all patients in the pacing group, the location and timing of the onset conformed to the positions and timing of electrodes (100%). In patients with WPW syndrome, abnormal onset was localized to portions of the ventricular wall other than the upper IVS at the delta wave or within 25 ms after the delta wave in the ECG. The agreement was 90% (18 of 20) between the abnormal onset and the position of the accessory pathways determined by ICEP testing. CONCLUSIONS: These results suggest that TDAI is a useful noninvasive method that frequently is successful in visualizing the intramural site of origin of ventricular mechanical contraction.  (+info)

Dispersion of signal-averaged P wave duration on precordial body surface in patients with paroxysmal atrial fibrillation. (3/507)

AIMS: This study sought to investigate whether the spatial dispersion of signal-averaged P wave duration would be increased in patients with paroxysmal atrial fibrillation, by use of precordial mapping of the P wave signal-averaged ECG. METHODS AND RESULTS: The P wave signal-averaged ECG was recorded by the P wave-triggering method from 16 precordial leads in 55 patients with paroxysmal atrial fibrillation and 57 control subjects. As an index of the dispersion of signal-averaged P wave duration, we obtained the difference between the maximum and minimum in 16 recording sites. The dispersion was significantly greater in the patients with paroxysmal atrial fibrillation than the controls (26.6 +/- 9.5 vs 14.8 +/- 6.7 ms, P<0.0001). In 25 patients with symptomatic attacks of paroxysmal atrial fibrillation, the signal-averaged ECG was repeated 1 h after a single dose of orally administered pilsicainide, a new class Ic drug. These patients were prospectively followed-up for 10 +/- 11 months with pilsicainide. The rate of freedom from recurrence of paroxysmal atrial fibrillation attacks was significantly (P<0.0001) higher in patients with whom dispersion was decreased by the single dose (54%[7/13]) than in those in whom dispersion increased (8%[1/12]). CONCLUSION: Increased dispersion of signal-averaged P wave duration would play an important role in generating paroxysmal atrial fibrillation and would be useful in the prediction of drug efficacy to evaluate the change in dispersion by a single administration of pilsicainide.  (+info)

Mapping and ablation of ventricular tachycardia with the aid of a non-contact mapping system. (4/507)

OBJECTIVE: Treatment of ventricular tachycardia (VT) in coronary heart disease has to date been limited to palliative treatment with drugs or implantable defibrillators. The results of curative treatment with catheter ablation have proved disappointing because the complexity of the VT mechanism makes identification of the substrate using conventional mapping techniques difficult. The use of a mapping technology that may address some of these issues, and thus make possible a cure for VT with catheter ablation, is reported. PATIENTS AND INTERVENTION: The non-contact system, consisting of a multielectrode array catheter (MEA) and a computer mapping system, was used to map VT in 24 patients. Twenty two patients had structural heart disease, the remainder having "normal" left ventricles with either fasicular tachycardia or left ventricular ectopic tachycardia. RESULTS: Exit sites were demonstrated in 80 of 81 VT morphologies by the non-contact system, and complete VT circuits were traced in 17. In another 37 morphologies of VT 36 (30)% (mean (SD)) of the diastolic interval was identified. Thirty eight VT morphologies were ablated using 154 radiofrequency energy applications. Successful ablation was achieved by 77% of radiofrequency within diastolic activation identified by the non-contact system and was significantly more likely to ablate VT than radiofrequency at the VT exit, or remote from diastolic activation. Over a mean follow up of 1.5 years, 14 patients have had no recurrence of VT and only two target VTs have recurred. Five patients have had recurrence of either slower non-sustained, undocumented or fast non-target VT. Five patients have died, one from tamponade from a pre-existing temporary pacing wire, and four from causes unrelated to the procedure. CONCLUSION: The non-contact system can safely be used to map and ablate haemodynamically stable VT with low VT recurrence rates. It is yet to be established whether this system may be applied with equal success to patients with haemodynamically unstable VT.  (+info)

Low-frequency component of body surface potential maps identifies patients at risk for ventricular tachycardia. (5/507)

AIMS: To investigate the ability of spectral features of signal-averaged body-surface potential maps in identifying post-infarction patients who are at risk of developing ventricular tachycardia. METHODS AND RESULTS: We recorded 120 lead body surface potential maps during sinus rhythm in 135 subjects (45 patients with healed myocardial infarction but no history of ventricular tachycardia, 45 patients with both healed myocardial infarction and at least one episode of sustained ventricular tachycardia, and 45 normal subjects) and analysed spectral features of body surface potential maps selected on the basis of isoharmonic maps for given bands of the frequency spectrum. We found that in the low-frequency band (1-11 Hertz), the group-mean power spectra of leads located at isoharmonic map maxima were significantly different (P<0.0001) between the two groups of myocardial infarction patients. We estimated that this single feature alone can prospectively identify myocardial infarction patients at risk for ventricular tachycardia with a predictive accuracy of 74+/-6%. CONCLUSION: Our results suggest that the bulk of diagnostic information associated with arrhythmogenicity resides in the low-frequency band of the power spectrum. This finding is at variance with the established notion that only the high-frequency component of signal-averaged electrocardiograms carries such information.  (+info)

Signal averaged electrocardiography of Japanese. (6/507)

Although studies show that the ventricular tachycardia and sudden cardiac deaths caused by ischemic heart diseases affect Japanese less than Westerners, predictive accuracy of the signal averaged ECG for ventricular tachycardia and sudden cardiac deaths are almost the same as the results for Westerners. The recent prognosis of ischemic heart diseases is showing improvements along with the development of re-perfusion therapy, which is changing the significance of the signal averaged ECG. Therefore a clinical use for signal averaged ECG should be discussed in cases of cardiomyopathy which cause sudden cardiac deaths and other heart diseases. So it is necessary to redetermine normal values of the signal averaged ECG parameters. In this article, the following was reviewed on the basis of our studies regarding the clinical significance of the signal averaged ECG of Japanese and normal signal averaged ECG values. (1) System and gender specific differences on signal averaged ECG of Japanese, (2) His-Purkinje system, pre-P deflection and atrial late potential on signal averaged ECG, (3) Ventricular late potentials of Japanese.  (+info)

Use of electroanatomic mapping to delineate transseptal atrial conduction in humans. (7/507)

BACKGROUND: Interaction between wave fronts in the right and left atrium may be important for maintenance of atrial fibrillation, but little is known about electrophysiological properties and preferential routes of transseptal conduction. METHODS AND RESULTS: Eighteen patients (age 44+/-12 years) without structural heart disease underwent right atrial electroanatomic mapping during pacing from the distal coronary sinus (CS) or the posterior left atrium. During distal CS pacing, 9 patients demonstrated a single transseptal breakthrough near the CS os, 1 patient in the high right atrium near the presumed insertion of Bachmann's bundle and 1 patient near the fossa ovalis. The mean activation time from stimulus to CS os was 48+/-15 ms compared with 86+/-15 ms to Bachmann's bundle insertion (P<0.01) and 59+/-23 ms to the fossa ovalis (P=NS and P<0.01, respectively). During left atrial pacing, the earliest right atrial activation was near Bachmann's bundle in 5 and near the fossa ovalis in 4 patients. The activation time from stimulus to CS os was 70+/-15 ms compared with 47+/-16 ms to Bachmann's bundle (P<0.01) and 59+/-25 ms to the fossa ovalis (P=NS). Whereas the total septal activation time was not significantly different during CS pacing compared with left atrial pacing (41+/-16 versus 33+/-17 ms), the total right atrial activation time was longer during CS pacing (117+/-49 versus 79+/-15 ms; P<0.05). CONCLUSIONS: Three distinct sites of early right atrial activation may be demonstrated during left atrial pacing. These sites are in accord with anatomic muscle bundles and may have relevance for maintenance of atrial flutter or fibrillation.  (+info)

Computer-assisted animation of atrial tachyarrhythmias recorded with a 64-electrode basket catheter. (8/507)

OBJECTIVES: The aim of this study was to assess the value of a new mapping technique based on computer-assisted animation of multielectrode basket catheter (BC) recordings in patients with atrial arrhythmias. BACKGROUND: The three-dimensional activation patterns of cardiac arrhythmias are not completely understood owing to limitations of conventional mapping techniques. METHODS: The study included 32 patients with atrial tachycardia (AT) and 38 patients with atrial flutter (AFL). A software program was developed to analyze the activation patterns based on 56 bipolar electrograms recorded with a 64-electrode BC deployed in the right atrium (RA). RESULTS: The total time needed for the animation of activation patterns of atrial arrhythmias was 5 +/- 0.8 min. In 22 patients with right AT, the animated maps revealed that arrhythmia was unifocal in 15 patients, multifocal in 2 patients, polymorphic in 4 patients and reentrant in 1 patient. In 10 patients with left AT, breakthroughs on the right side of the septum (2 in 8 patients and 1 in 2 patients) and a left-to-right activation of the RA were demonstrated. In patients with typical AF, the reentrant excitation was a broad activation front with preferential propagation around the tricuspid annulus. In patients with atypical AFL, the reentry circuit involved one of the venae cavae and a line of block located in the posterior wall. CONCLUSIONS: The computer-assisted animation of multiple electrograms recorded with a BC is a valuable mapping tool that delineates the three-dimensional activation patterns of various atrial arrhythmias. The technique is appropriate for complex, short-lived or unstable arrhythmias.  (+info)

METHODS AND RESULTS The present study compares 120-lead body surface potential map (BSPM) data from 131 patients with acute MI and 159 normal control subjects (N). The MI population was stratified according to the location of ventricular wall motion abnormalities evidenced by radionuclide imaging into 76 patients with anterior MI (AMI), 32 patients with inferior MI (IMI), and 23 patients with posterior MI (PMI). BSPM were recorded within 24 hours of admission. Group mean BSPM of the ST segment were obtained for N, AMI, IMI, and PMI by sampling the time-normalized ST-T waveform at 18 equal intervals and averaging the voltages at each electrode site over the first five of these 18 ST-T time instants. Corresponding discriminant maps were also computed for each pairwise comparison (AMI versus N, IMI versus N, and PMI versus N) by subtracting the normal group mean voltages from each MI group mean voltages and by further dividing each resulting difference by the composite standard deviation calculated ...
Non-invasive diagnosis of acute myocardial infarction (AMI) associated with significant left main coronary artery stenosis (LMCAS) is challenging, with characteristic 12-lead ECG abnormalities of ST elevation (STE) in lead aVR, precordial T wave inversion (TWI) and/or ST depression (STD) having low diagnostic sensitivity. Methods Consecutive patients presenting to our unit with acute ischaemic-type chest pain from 2000-10 were analyzed. Entry criteria: 12-lead ECG and BSPM at presentation, cardiac troponin T (cTnT) ≤ 12h and coronary angiography during admission. Peak cTnT ≥0.03µg/L defined AMI. ECG abnormalities assessed: STEMI by Minnesota criteria; STE in lead aVR ≥0.5mm; STD ≥0.5mm in ≥2 contiguous leads (CL); TWI ≥1mm in ≥2CL. BSPM STE was: ≥2mm in anterior; ≥1mm in lateral, inferior, right ventricular (RV) or high right anterior (HRA); and ≥0.5mm in posterior territories. Angiographic luminal narrowing ≥70% defined significant LMCAS. Results Enrolled were 2810 ...

AU - Daly, Michael. PY - 2014/11/1. Y1 - 2014/11/1. N2 - Criteria have been developed and published for the detection of ST segment elevation myocardial infarction (STEMI) in the 12-lead electrocardiogram (ECG). In this study we report on an algorithm for the detection of ST segment elevation in body surface potential maps (BSPM). The algorithm seeks ST segment elevation, exceeding predefined thresholds, in two contiguous/adjacent leads. Thresholds are based upon the extension of existing 12-lead ECG criteria. The algorithm was applied to 45 subjects who had 120-lead BSPMs recorded during percutaneous transluminal coronary angioplasty (PTCA). The algorithm was capable of distinguishing between baseline ECGs and peak balloon inflation ECGs with a sensitivity of 84.4% and specificity of 86.7%. Standard ...

Ischemic heart disease is the single most frequent cause of death in. the world today. Electrocardiogram (ECG) exercise testing is a common. tool for diagnosing this disease. With the ECG exercise test one can. compare the recording of the electrical activity in the heart during. exercise and rest. A shift between the rest and exercise recording in. the segment of the heartbeat called the ST segment is used both for. diagnosing ischemia, and as input to cardiac computation methods.. Body surface potential mappings (BSPM) are ECG recordings at a greater. number of locations on the torso, and provides better detection and. localisation properties than the traditional 12-lead ECG. In BSPM and ECG,. noise and drift from various sources are recorded in addition to the. signal propagating from the heart. A model for this is:. BSPM=signal+noise+drift.. Before accurate measurements of the ST segments in a BSPM. can be made, the noise and drift in the recording must be reduced. while keeping the signal ...

ECG imaging is an emerging technology for the reconstruction of cardiac electric activity from non-invasively measured body surface potential maps. In this case report, we present the first evaluation of transmurally imaged activation times against endocardially reconstructed isochrones for a case of sustained monomorphic ventricular tachycardia (VT). Computer models of the thorax and whole heart were produced from MR images. A recently published approach was applied to facilitate electrode localization in the catheter laboratory, which allows for the acquisition of body surface potential maps while performing non-contact mapping for the reconstruction of local activation times. ECG imaging was then realized using Tikhonov regularization with spatio-temporal smoothing as proposed by Huiskamp and Greensite and further with the spline-based approach by Erem et al. Activation times were computed from transmurally reconstructed transmembrane voltages. The results showed good qualitative agreement ...
Objectives. This study examined the performance of the 62-lead body surface electrocardiogram (ECG) in identifying the site of origin of ventricular tachycardia in patients with a previous myocardial infarction.. Background. Because the accuracy of ECG localization of ventricular tachycardia using standard 12-lead recordings is restricted to the identification of rather large ventricular areas, application of multiple torso lead recordings may augment the resolving power of the surface ECG and result in more discrete localization of arrhythmogenic foci.. Methods. Thirty-two patients were selected for electrophysiologically guided ablative therapy for drug-resistant postinfarction ventricular tachycardia. In these patients, QRS integral maps of distinct monomorphic ventricular tachycardia configurations were correlated with a previously generated infarct-specific reference data base of paced QRS integral maps. Each paced pattern in the data base corresponded with ectopic endocardial impulse ...
TY - JOUR. T1 - Molecular electrostatic potential mapping and structure-activity relationship for 3-methoxy flavones. AU - Santhosh, C.. AU - Mishra, P. C.. PY - 1996/12/1. Y1 - 1996/12/1. N2 - Molecular electrostatic potential (MEP) maps of certain 3-methoxy flavone derivatives having different anti-picornavirus activities have been studied. Geometries of the molecules were optimised and charge distributions computed using the AMI molecular orbital method. Hybridization displacement charges (HDC) were combined with the Löwdin charge distributions to compute the MEP maps. Reliability of the method of computing MEP maps was tested by studying certain other molecules for which ab initio MEP results are available. The anti-picornavirus activities of the flavones have been shown to be related with negative MEP values in two regions, one near the 3-methoxy group and another in a diagonally opposite region near the substituent attached to the C7 atom of the molecules.. AB - Molecular electrostatic ...

BACKGROUND AND PURPOSE: Understanding drug effects on the heart is key to safety pharmacology assessment and anti-arrhythmic therapy development. Here our goal is to demonstrate the ability of computational models to simulate the effect of drug action on the electrical activity of the heart, at the level of the ion-channel, cell, heart and ECG body surface potential. EXPERIMENTAL APPROACH: We use the state-of-the-art mathematical models governing the electrical activity of the heart. A drug model is introduced using an ion channel conductance block for the hERG and fast sodium channels, depending on the IC(50) value and the drug dose. We simulate the ECG measurements at the body surface and compare biomarkers under different drug actions. KEY RESULTS: Introducing a 50% hERG-channel current block results in 8% prolongation of the APD(90) and 6% QT interval prolongation, hERG block does not affect the QRS interval. Introducing 50% fast sodium current block prolongs the QRS and the QT intervals by 12% and

Non-contact mapping was used in 17 patients, electroanatomic mapping in 36, and both noncontact and electroanatomic mapping in 15. Arrhythmias ...
To evaluate the source of ST depression, a sheep model of subendocardial ischaemia using partial coronary artery ligation coupled with atrial pacing was developed. Ischaemia was induced initially in either the left anterior descending coronary artery or the left circumflex coronary artery territory and subsequently in the territory of the other vessel. The ischaemic regions were documented by a fluorescent microsphere technique. During ischaemia potentials were mapped simultaneously from the endocardium and the epicardium. The distributions of epicardial potentials from either ischaemic source were very similar (0.77±0.14, P,0.0001), both showing ST depression on the free wall of the left ventricle, and no association between the ST depression and the ischaemic region. At the same time, the endocardial ST elevation was directly associated with the region of reduced blood flow. Insulating the heart from the surrounding tissue with plastic increased the magnitude of epicardial and endocardial ST ...
Optical potential energy landscapes created using acousto-optical deflectors are characterized via solvent-driven colloidal particles. The full potential energy of both single optical traps and complex landscapes composed of multiple overlapping traps are determined using a simple force balance argument. The potential of a single trap is shown to be well described by a Gaussian trap with stiffness found to be consistent with those obtained by a thermal equilibrium method. We also obtain directly the depth of the well, which (as with stiffness) varies with laser power. Finally, various complex systems ranging from double-well potentials to random landscapes are generated from individually controlled optical traps. Predictions of these landscapes as a sum of single Gaussian wells are shown to be a good description of experimental results, offering the potential for fully controlled design of optical landscapes, constructed from single optical traps.. © 2012 Optical Society of America.

One of the problems with applying these data clinically might be the extra-invasive procedure (insertion of the non-contact balloon to the left ventricle) and the subsequent time and cost. Theoretically it would be very useful to perform non-contact mapping during the implant procedure in order to identify the area of latest activation not obstructed by conduction block and scar. This would also allow the operator to pass the catheter locator signal produced by the non-contact mapping system through the left ventricular lead and therefore steer it to that site. However, at the present time it is recommended that the patient is heavily anticoagulated while the non-contact balloon is in the left heart which would prevent safe implantation of the CRT system.. Fung and colleagues14 have gone some way to try and overcome this problem by comparing non-contact mapping data to tissue Doppler imaging. They found that latest activation on non-contact and tissue Doppler correlated well. They did not ...

This paper proposes a multiobjective application mapping technique targeted for large-scale network-on-chip (NoC). As the\nnumber of intellectual property (IP) cores inmultiprocessor system-on-chip (MPSoC) increases, NoC application mapping to find\noptimum core-to-topology mapping becomes more challenging. Besides, the conflicting cost and performance trade-off makes\nmultiobjective application mapping techniques even more complex. This paper proposes an application mapping technique that\nincorporates domain knowledge into genetic algorithm (GA). The initial population of GA is initialized with network partitioning\n(NP) while the crossover operator is guided with knowledge on communication demands. NP reduces the large-scale application\nmapping complexity and providesGAwith a potential mapping search space.The proposed genetic operator is comparedwith stateof-\nthe-art genetic operators in terms of solution quality. In this work, multiobjective optimization of energy and thermal-balance\nis ...
Rapid atrial arrhythmias such as atrial fibrillation (AF) predispose to ventricular arrhythmias, sudden cardiac death and stroke. Identifying the origin of atrial ectopic activity from the electrocardiogram (ECG) can help to diagnose the early onset of AF in a cost-effective manner. The complex and rapid atrial electrical activity during AF makes it difficult to obtain detailed information on atrial activation using the standard 12-lead ECG alone. Compared to conventional 12-lead ECG, more detailed ECG lead configurations may provide further information about spatio-temporal dynamics of the body surface potential (BSP) during atrial excitation. We apply a recently developed 3D human atrial model to simulate electrical activity during normal sinus rhythm and ectopic pacing. The atrial model is placed into a newly developed torso model which considers the presence of the lungs, liver and spinal cord. A boundary element method is used to compute the BSP resulting from atrial excitation. Elements of ...
based partly on calcrxc.hoc,v 1.3 2008/12/02 22:03:59 /* Calculates the effect of a uniform extracellular field on the extracellular potential adjacent to the membrane of a model neuron. Assume a uniform field with orientation specified by polar coordinates: phi is the angle between the field vector and the z axis. theta is the angle between the x axis and the projection of the field vector onto the x axis. The isopotential surfaces are perpendicular to the orientation of the field, and uniformly spaced. Without loss of generality, we may assume that the potential is 0 for all points on the isopotential surface that passes through (0,0,0). Let this be called the zero potential plane. The potential at any point xyz is proportional to the distance of that point from the zero potential plane. The distance is given by the dot product of the vector from (0,0,0) to (x,y,z) p = x*ux + y*uy + z*uz with the fields unit vector (i.e. the unit vector that is orthogonal to the zero potential plane): ufield ...
Pyloric motor neurons synapse at multiple sites along pyloric muscle fibers (Atwood et al., 1977, 1978; Atwood and Wojtowicz, 1986).A priori, two explanations for the EJP amplitude variability reported here thus exist. One is that the muscle fibers are essentially isopotential (fiber length less than two length constants) and the variability arises from variability in vesicle number released at each synaptic site during each spike. Given the large number of synaptic sites and large variation in quantal number observed at some crustacean synapses (Atwood and Wojtowicz, 1986), this variation would give rise to the smooth variation in EJP amplitude we observe. However, the short λ measured with multiple penetrations contradicts this explanation, because these data imply that the muscle fiber is not isopotential, and hence different synaptic sites are electrically isolated from each other. Pyloric muscle diameter is such that relatively small changes in membrane resistance would induce large length ...
We present a new image integration technique for flash and long-exposure image pairs to capture a dark scene without incurring blurring or noisy artifacts. Most existing methods require well-aligned images for the integration, which is often a burdensome restriction for practical use. We address this issue by locally transferring the colors of the flash images using a small fraction of corresponding pixels in the long-exposure images. We formulate image integration as a convex optimization problem with the local linear model. The proposed method makes it possible to integrate the color of the long-exposure image with the detail of the flash image without causing any harmful effects to its contrast, where the images do not need perfect alignment by virtue of our new integration principle. We show our method successfully outperforms the state-of-the-art in image integration and reference based color transfer for challenging misaligned datasets. ...

Air temperature: -2.2°C. In the late evening, the ship left iceberg C-18A and traveled east in search of an area away from the influence of icebergs. The principal investigators monitored the ships data systems during the transit to select the study area. When the ship reached a suitable location about 75 kilometers away, a suite of sampling began to characterize the area. First, the MOCNESS net system was deployed for several hours and recovered before sunrise. While the MOCNESS crew sorted samples in the lab, other research teams conducted water collections with trace-metal-clean Niskin bottles, surface mapping, and CTD casts throughout the day. Just after dinner, a Langrangian sediment trap was lowered into the water and started on a three-day drift at 600 meters depth.

Anatomically accurate and biophysically detailed bidomain models of the human heart have proven a powerful tool for gaining quantitative insight into the links between electrical sources in the myocardium and the concomitant current flow in the surrounding medium as they represent their relationship mechanistically based on first principles. Such models are increasingly considered as a clinical research tool with the perspective of being used, ultimately, as a complementary diagnostic modality. An important prerequisite in many clinical modeling applications is the ability of models to faithfully replicate potential maps and electrograms recorded from a given patient. However, while the personalization of electrophysiology models based on the gold standard bidomain formulation is in principle feasible, the associated computational expenses are significant, rendering their use incompatible with clinical time frames. In this study we report on the development of a novel computationally efficient ...
Brain electric field data (EEG and event-related potentials [ERP]) recorded simultaneously from many electrodes (locations) on the human head surface can be viewed as series of maps of the momentary spatial distributions of electric potential, as potential landscapes (Lehmann, 1971, 1972). Typically, 128 to 512 maps per second are used. The historical and unfortunate discussions in the EEG community about the choice of a presumable inactive electric reference location are not an issue here, because a given landscape cannot be changed by the location of the point from which it is measured; this choice merely determines the value labels of the isopotential lines - quite like the rising or receding water level of a lake in a mountainous area changes the location of the zero water level mark, but not the landscape (Lehmann, 1987; Geselowitz, 1998). Over time, the potential landscapes vary in electric strength. Map Hilliness (Lehmann, 1971) assesses map strength; it is defined as the sum of the ...
A lead assembly adapted for endocardial fixation to a human heart is provided. The lead assembly includes a lead body that has a proximal end provided with a connector for electrical connection to a cardiac stimulator. The cardiac stimulator may be a pacemaker, a cardioverter/defibrillator, or a sensing instrument. The distal end of the lead body is connected to a tubular electrode housing. The lead body consists of a noncoiled conductor cable surrounded by a coextensive insulating sleeve. In contrast to conventional leads, the lead body of the present invention does not require coiled conductor wires or an internal lumen. Manipulation of the lead body is via an external guide tube. Lead body diameters of 0.25 mm or smaller are possible.
Surface mapping plays an important role in geometric processing, which induces both area and angular distortions. If the angular distortion is bounded, the mapping is called a quasiconformal mapping (
Gene therapy to repair damaged heart muscle is most likely to succeed if it can be injected at the site of ischemia where there is viable myocardium with reduced contractile ability, and a new technique that combines imaging and electroanatomical mapping does just that. A study of this novel approach that shows increased blood flow in treated areas in patients with refractory angina is published in Human Gene Therapy.

Pseudoaneurysm of thoracic aorta as a complication of blunt trauma to the chest, can present with a variety of symptoms due to mass compression effect. Here we report the first pseudoaneurysm of thoracic aorta presenting with chronic cough and inappropriate sinus tachycardia. The purpose of this case report is to highlight pseudoaneurysm of thoracic aorta as a rare differential diagnosis for inappropriate sinus tachycardia. Here we report a case of 29-year-old white woman, a nurse, with history of a motor vehicle accident. She initially presented to medical attention with inappropriate sinus tachycardia 2 years following the motor vehicle accident during her pregnancy. Six years later she underwent sinoatrial node modification after failing a number of medications. Days prior to the ablation she developed a mild cough which became constant within a week following ablation. A computed tomography scan of her chest performed as part of a workup revealed an outpouching of the inferomedial aspect of the
Optical tweezers (OT) are widely used for pico (and femto)-Newton range force measurements. The appropriate choice of the bead size is not well understood for biopolymer stretching applications of OT. We have shown, both by theory and experiment, that wrong choice of the bead size could cause errors as large as 295% in the measured force. We provide a simple map for correct choice of the bead size and the direction of pulling for such applications. There is a good agreement between our theoretical and experimental results.. © 2013 Optical Society of America. Full Article , PDF Article ...
Inappropriate sinus tachycardia (IST) is a nonparoxysmal arrhythmia characterized by either a continuous sinus tachycardia or intermittent periods of inappropriately rapid sinus rates.
Inappropriate sinus tachycardia (IST) is a non-paroxysmal arrhythmia, characterized by a persistently high sinus heart rate (HR) and/or an exaggerated HR response to minimal exertion, and can be responsible for palpitations, asthenia, chest pain, dizziness and syncope, which can be highly invalidating. Conventional treatment of IST, targeted to symptoms control, mainly consists on β-blockers. However, these drugs are often insufficient or not well tolerated because of side effects (mostly hypotension) that usually limit the administered dose. Ivabradine, a sinus rate lowering agent currently employed in Europe in the treatment of stable angina and chronic heart failure, has recently been demonstrated to be effective and safe in the treatment of IST by a few case reports and clinical trials. A randomized clinical trial comparing ivabradine to β-blockers has not be performed yet ...

0154] FIG. 20 is an illustration of an exemplary application of functional imaging and non-invasive electrical potential mapping according to a method of the present invention. As will be appreciated, the system and methodology of the present invention allow for both functional imaging of biological objects 19 and mapping of electrical excitation within biological tissues 19. This may be achieved as a two-step imaging process, as illustrated in FIG. 20. First, the system 100 is used as an electromagnetic tomographic imaging tool for non-invasive assessment of functional and pathological conditions of a biological object 19 and the location of any areas of diseased tissues 19. For example, in FIG. 20, cardiac tissue with suspicious areas of myocardium is functionally imaged in Step 1 to identify areas of ischemia/infarction. Second, if the location of a diseased target is within a biologically excited tissue 19 (such as cardiac tissue, nervous tissue, musculoskeletal tissue, or the like), then a ...
The techniques of theoretical chemistry have been used to elucidate the molecular properties and modes of receptor binding that modulate receptor affinity and antagonist activity of the beta-carbolines, a class of potent benzodiazepine antagonists. Six analogs were chosen in order to investigate the role of the amine (NH) group, the aromatic nitrogen, and the C3-substituent in determining receptor affinities. Electrostatic potential mapping and characterization of explicit drug-receptor interactions have led to the hypothesis that simultaneous interaction of a model cationic arginine site with the N2 and C3-substituents could play a key role in determining receptor affinities. The electron-withdrawing effects of C3-substituents on the amine nitrogen appear less important, though interactions of these groups with an anionic glutamate or aspartate site could also occur at the receptor. Similarly, stacking interactions with neutral or cationic aromatic residues such as tryptophan or protonated ...

The mechanism of post-infarct SMVT is scar-related re-entry in the majority of patients (1). Inhomogeneous scarring with varying degrees of subendocardial myocardial fiber preservation within dense zones of fibrosis leads to slowed conduction, nonuniform anisotropy, and the potential for channels within the scar zone-conditions necessary for the development of re-entry (2,3). In the ablation era, high-density electroanatomic mapping has been used to characterize the electrical correlates of this well-described pathologic substrate, allowing for development of substrate modification strategies (7) to target unmappable SMVTs (19). Channels within a scar (isolated potentials [6,11], very late potentials) or regions at the scar-border zone (putative exit sites) (18,20) appear to represent critical components of the re-entrant circuit and have all been targeted with successful long-term ablation outcomes.. The current study compares these key markers of SMVT substrate by creating high-density maps of ...

In the voltageclamp configuration, a current is injected into the cell via a negative feedback loop to compensate changes in membrane potential. This technique is the refinement of the voltage clamp. Neuroscience is available from oxford university press. Sep 29, 20 this screencast describes iv and vi relations derived from patch or current clamp data, and how to calculate conductance or resistance from the data. Still more recently, a technique has been invented, patch clamping, that makes it possible to voltage clamp small regions of the nerve cell membrane, and look at the responses of individual ion channels to changes in voltage across the membrane. Oct 28, 20 the voltage clamp is a technique used to control the voltage across the membrane of a small or isopotential area of a nerve cell by an electronic feedback circuit. Alternatively, the current clamp technique can be used. Identification and regulation of wholecell chloride currents. Theory the basis of the voltage clamp may be ...

Hi everyone. I havent posted in a very long time, but I experienced HELLP with my pregnancy back in November of 2010. Since then there have been several tests for autoimmune disorders and other things, all which have come back normal. However, I have had fairly frequent heart palpitations since the birth of my son. I actually got them prior to my pregnancy, but they would be very they occur more frequently. After wearing a heart monitor, it looks like I am basically experiencing inappropriate sinus tachycardia. This isnt a very serious thing from what I gather, but I am on a low dose beta-blocker to help with the symptoms ...

To demonstrate this potential, clusters of contracting cardiomyocytes isolated from the differentiation cultures were transplanted into the left ventricle of pigs that had their atrioventricular node ablated. The recipient hearts had spontaneous rhythms that appeared to originate from the transplanted cells as assessed by high-resolution electroanatomical mapping. Though promising, these results also raise the concern that transplanted cells could serve as a nidus for arrhythmia. Other mesoderm-derived lineages. While the hematopoietic, vascular, and cardiac lineages have been studied in most detail, the ES cell system does offer the potential to develop many other mesoderm lineages. To date, cell populations representing the skeletal muscle (Rohwedel et al. 1994 ...
