When I asked Hubel and Kiang for advice on where to apply to graduate school in neuroscience, their only point of agreement was that the top places were Cambridge, MA and Cambridge, UK. I felt it was time to leave Cambridge, MA to broaden my horizons, so I applied for a Marshall Scholarship to go to the other Cambridge. In early 1972, while still a senior at Harvard, I learned my application was successful, and that my Ph.D. supervisor would be a Dr. R. H. Adrian, whom I had never heard of. I phoned my brother Dick, who had just become an Assistant Professor at Yale after finishing his D. Phil. from Oxford on cardiac electrophysiology. Dick informed me that R. H. Adrian was one of Britains most eminent skeletal muscle electrophysiologists, and son of E. D. Adrian, a Nobel Laureate in neurophysiology. Moreover R. H. Adrian had been the external examiner on Dicks D. Phil. degree. But muscle is a backwater, I exclaimed. I want to work on the brain. Dick assured me that Richard Adrian was a ...

The sodium-potassium pump is widely recognized as the principal mechanism for active ion transport across the cellular membrane of cardiac tissue, being responsible for the creation and maintenance of the transarcolemmal sodium and potassium gradients, crucial for cardiac cell electrophysiology. Importantly, sodium-potassium pump activity is impaired in a number of major diseased conditions, including ischemia and heart failure. However, its subtle ways of action on cardiac electrophysiology, both directly through its electrogenic nature and indirectly via the regulation of cell homeostasis, make it hard to predict the electrophysiological consequences of reduced sodium-potassium pump activity in cardiac repolarization. In this review, we discuss how recent studies adopting the systems biology approach, through the integration of experimental and modeling methodologies, have identified the sodium-potassium pump as one of the most important ionic mechanisms in regulating key properties of cardiac

BACKGROUND: In MERLIN TIMI-36, ranolazine (RAN) reduced the indicidence of new onset AF (Scirica et al, Circ 2007;116:1647). At therapeutic concentrations, RAN inhibits the persistent sodium current. At higher concentrations, RAN also inhibits IKs, IKr and late ICaL. We investigated the effects RAN on cardiac electrophysiology in a goat model of AF. In this model, AF itself leads to a progressive shortening of the effective refractory period (ERP) and a gradual increase in AF stability.. METHODS: Arrays of atrial epicardial electrodes were implanted in 7 Dutch milk goats. After recovery, experiments were performed at baseline and after 2 and 14 days of artificially maintained AF. At these time points, RAN was infused intravenously for 1 hour to result in plasma concentrations of 4, 8 and 16 uM. ECG parameters, ERP, conduction velocity (CV), AF cycle length (AFCL) and AF episode duration (AFdur) were determined.. RESULTS: The main parameters are summarized in the table⇓. At baseline and after 2 ...

In this meta-analysis of randomized, double-blind, placebo-controlled clinical trials, fish oil consumption reduced HR in humans. Although the overall effect was modest (1.6-bpm reduction), on a population level, even modest differences in risk factors can have a significant impact on health. These findings provide firm evidence for an effect of fish oil consumption on cardiac electrophysiology in humans.. The regulation of HR is a complex physiological process, with components related to vagal tone, sympathetic input, responsiveness of the sinus node, and systolic and diastolic left ventricular function. The decrease in HR with fish oil consumption indicates that marine n-3 fatty acids influence at least 1 of these parameters. The n-3 fatty acids are incorporated into myocyte membranes and may influence ion channel function9,10; this could directly alter the automaticity or responsiveness of the sinus node. Fish oil also lowers blood pressure in humans,57 possibly by reducing systemic vascular ...

The key objective of this work is the design of an unconditionally stable, robust, efficient, modular, and easily expandable finite element-based simulation tool for cardiac electrophysiology. In contrast to existing formulations, we propose a global-local split of the system of equations in which the global variable is the fast action potential that is introduced as a nodal degree of freedom, whereas the local variable is the slow recovery variable introduced as an internal variable on the integration point level. Cell-specific excitation characteristics are thus strictly local and only affect the constitutive level. We illustrate the modular character of the model in terms of the FitzHugh-Nagumo model for oscillatory pacemaker cells and the Aliev-Panfilov model for non-oscillatory ventricular muscle cells. We apply an implicit Euler backward finite difference scheme for the temporal discretization and a finite element scheme for the spatial discretization. The resulting non-linear system of ...

Of 111,293 ICD (implantable cardiac defibrillator) implantations included in the analysis, 78,857 (70.9%) were performed by electrophysiologists, 24,399 (21.9%) by nonelectrophysiologist cardiologists, 1,862 (1.7%) by thoracic surgeons, and 6,175 (5.5%) by other specialists. Compared with patients whose ICD was implanted by electrophysiologists, patients whose ICD was implanted by either nonelectrophysiologist cardiologists or thoracic surgeons were at increased risk of complications in both unadjusted (electrophysiologists, 3.5% [2743/78 857]; nonelectrophysiologist cardiologists, 4.0% [970/24 399]; thoracic surgeons, 5.8% [108/1862]; P < .001) and adjusted analyses (relative risk [RR] for nonelectrophysiologist cardiologists, 1.11 [95% confidence interval {CI}, 1.01-1.21]; RR for thoracic surgeons, 1.44 [95% CI, 1.15-1.79]). ...

In this study, we modified the traditional relationship between resistive and conductive heating used for conventional RF ablation, delivering immediate and lethal heating to a similar tissue depth affected by conventional ablation in the atria. The results from computer thermal modeling were confirmed by experimental data in animals, including histological analysis.. It is important to note that HP-SD ablation is particularly suited for thin-walled structures, such as the atrium, and particularly the PV circumference. However, it may not be suitable for thicker tissue, either in the atria, such as the mitral annulus (i.e., for mitral lines), or for ablation in the ventricle. HP-SD ablation is largely based on immediate heat formation during the resistive phase, affecting a tissue depth of ≤3.5 to 4 mm using the energy settings evaluated in this study. Studies of human cadavers have shown that the thickness of the left atrium including the PV circumference is consistently ≤4 mm (6,15). In ...

LV endocardial pacing has been proposed and has been shown to be superior to conventional LV epicardial pacing in the CRT setting in computer simulations (54) and preclinical experiments (55,56). In various canine LBBB models, superiority has been shown in electrical resynchronization and acute hemodynamic response (55,56). However, clinical studies showed less reproducible differences. Derval et al. (57) was not able to show significantly better hemodynamic response between pacing in the endocardial position and immediately below the position of the coronary sinus lead, although in each patient there was an endocardial position that resulted in superior improvement in pump function. Similarly, Spragg et al. (58) found that endocardial pacing tended to be superior to epicardial pacing in patients with ischemic cardiomyopathy, but that the location of optimal LV endocardial pacing varied among patients. Shetty et al. (59) showed that LV endocardial pacing was superior to epicardial pacing and ...

Cardiac arrhythmias are becoming one of the major health care problem in the world, causing numerous serious disease conditions including stroke and sudden cardiac death. Furthermore, cardiac arrhythmias are intimately related to the signaling ability of cardiac cells, and are caused by signaling defects. Consequently, modeling the electrical activity of the heart, and the complex signaling models that subtend dangerous arrhythmias such as tachycardia and fibrillation, necessitates a quantitative model of action potential (AP) propagation. Yet, many electrophysiological models, which accurately reproduce dynamical characteristic of the action potential in cells, have been introduced. However, these models are very complex and are very time consuming computationally. Consequently, a large amount of research is consecrated to design models with less computational complexity. This paper is presenting a new model for analyzing the propagation of ionic concentrations and electrical potential in space and

First of all, the proper monitoring must be determined with a specific individual dedicated to monitoring the patient during sedation and analgesia. When moderate sedation is planned, an individual with advanced cardiac life support skills (plus certified and experienced in sedation) must be immediately available. All significantly invasive electrophysiology procedures (e.g., nonsubcutaneous implants, electrophysiology studies and ablation procedures, and high voltage shock delivery procedures) must include monitoring of blood pressure (BP), end-tidal CO2 (ETCO2), oxygen saturation (SaO2), and a multichannel ECG.. Additionally, temperature monitoring may be required for some procedures. Certain procedures may need additional indwelling catheters to measure central venous pressure (CVP), continuous arterial pressure, and pulmonary artery pressure. These intravascular lines also permit arterial blood gas sampling. Additional monitoring also may be required to assess the level of anticoagulation ...

I think I mentioned that heart disease is a very personal cause because it has affected my family for decades. Did I ever mention that my Dad has died more than a few times? Well, he has and his last episode was caused by SADS. Thankfully, he is one of the rare lucky survivors due to a defibrillator close by.. A horrible sounding name, that conjures up unpleasant thoughts. So what is SADS? It is an acronym for Sudden arrhythmia death syndromes. (SADS) are genetic heart conditions that can cause sudden death in young, apparently healthy people and takes approximately 4,000 young lives annually These conditions can be treated and deaths can be prevented.. In case your interested here are the warning signs: family history of unexpected, unexplained sudden death under age 40; fainting or seizure during exercise, excitement or startle; consistent or unusual chest pain &/or shortness of breath during exercise. My Dad was on a spin bike when his heart stopped almost 2 years ago.. Until then, I had no ...

Warfarin remains the most efficacious therapy available to prevent stroke in the setting of AF (1-3). However, several substantial limitations of the drug have motivated research to develop superior alternatives. Perhaps most important, warfarin is associated with an increased risk of hemorrhagic stroke. In addition, the food and drug interactions and need for ongoing monitoring make the drug particularly difficult for patients to take. This year, several studies examining new therapies for stroke prevention in the setting of AF were published.. The first study is the first published major trial of a direct thrombin inhibitor since the SPORTIF (Stroke Prevention using an ORal Thrombin Inhibitor in atrial Fibrillation) studies examining ximelagatran. Although ximelagatran appeared to be similar to warfarin in efficacy and bleeding risk, it resulted in hepatotoxicity (4). Connolly et al. (5) published the RE-LY (Randomized Evaluation of Long-Term Anticoagulation Therapy) study, a randomized trial ...

Wes: Why make a better bad idea. MOC is not board Certification, which was conceived as a lifelong status awarded to those who attained consultant status as is printed on my 1989 original certificate. MOC is a subscription program designed to capture all physicians into a CME monopoly for the ABMS and affiliates. This is a $2.5 billion industry whereas ABMS is only a $350 million industry in 2011 (last IRS documents available). Nothing wrong with lifelong certification and lifelong learning, I have the problem iwth extortion of all physicians by a handful of colleagues who rarely practice medicine at the bedside but hope to expand their industry profits at great cost to all physicians and patients, when healthcare must get cheaper, not MORE expensive.

Due to advances in corrective surgery, congenital heart disease has an ever growing patient population. Atrial arrhythmias are frequently observed pre- and post-surgical correction. Pharmaceutical antiarrhythmic therapy is not always effective, therefore many symptomatic patients undergo catheter ablation therapy. In patients with atrioventricular septal defects (AVSD), ablation therapy itself has mixed success; arrhythmogenic recurrences are common, and because of the anatomical displacement of the atrioventricular node, 3-degree heart block post-ablation is a real concern. In order to develop optimal and safe ablation strategies, the field of congenital cardiac electrophysiology must combine knowledge from clinical electrophysiology with a thorough understanding of the anatomical substrates for arrhythmias. Using image-based analysis and multi-cellular mathematical modeling of electrical activation, we show how the anatomical alterations characteristic of an AVSD serve as arrhythmogenic ...

Background: This study assessed the cardiac electrophysiological and hemodynamic effects of an intravenous infusion of the combined ion channel blocker AZD1305. Methods: After successful ablation of atrial flutter, patients were randomized to receive placebo (n = 12) or AZD1305 (n = 38) in 4 ascending dose groups. Electrophysiological and hemodynamic measurements were performed before and commencing 20 minutes after start of infusion. Results: Left atrial effective refractory period increased dose and the primary outcome measure increased dose and plasma concentration dependently, with a mean increase of 55 milliseconds in dose group 3. There was a corresponding increase in right atrial effective refractory period of 84 milliseconds. The right ventricular effective refractory period and the paced QT interval also increased dose and concentration dependently, by 59 and 70 milliseconds, respectively, in dose group 3. There were indications of moderate increases of atrial, atrioventricular nodal, ...

Being overweight or obese throughout adulthood, especially during early adulthood, may lead to an increased risk of sudden cardiac death, according to a study published Nov. 25 in JACC: Clinical Electrophysiology.. Researchers led by Stephanie Chiuve, ScD, an assistant professor of medicine at Harvard Medical School, analyzed data from the Nurses Health study, following 72,484 healthy women from 1980 to 2012. Over the study period, researchers documented 445 cases of sudden cardiac death, 1,286 cases of fatal coronary heart disease, and 2,272 non-fatal myocardial infarction (MI). Results showed women who were overweight (body mass index [BMI] 25-30) and obese (BMI 30 or greater) were 1.5- and 2-times more likely, respectively, to experience sudden cardiac death over the next two years as compared to women with a healthy weight (BMI 21-23).. Further, women who were overweight or obese at the start of the study or obese at age 18 had an elevated risk of sudden cardiac death over the entire course ...

Why did you choose to specialise in electrophysiology? I started as a medical student at Dr. Chiel Janses (former Wilhelmina Gasthuis, University of Amsterdam) experimental EP lab in Amsterdam in 1978.. I was immediately in love with cardiac electrophysiology (EP) for its natural beauty, especially ECG tracings and mechanisms derived from them. I felt a strong attraction because one can understand quite quickly what is happening in the heart from these arrhythmia tracings and at the same time you feel the abundance of unanswered questions. At that time EP started to grow exponentially while a summary of experimental EP could still be grasped from one book Electrophysiology of the heart by Brian Hoffman and Paul Cranefield.. Throughout your career, what have been the biggest developments in electrophysiology?. The very introduction of computerised recording and analysis of EP signals from the hearts surface in 1978, derived from simultaneously recorded signals using custom made ...

For ACC members, the overall potential impact of this program is large. Five JACC Journals (JACC, JACC: Clinical Electrophysiology, JACC: Heart Failure, JACC: Cardiovascular Imaging, and JACC: Cardiovascular Interventions) feature monthly CME/MOC offerings. JACC: Basic to Translational Science, published bimonthly, also offers credit opportunity with each issue. Through JACC Journals alone, members could earn a total of 66 CME/MOC credits each year - more than enough to provide all the CME credits required by most states for medical licensure renewal (usually 25 credits per year), and more than enough to cover the ABIM Part II credit requirement of 100 credits for each five-year period.. Each JACC journal has at least one designated CME editor. Ragavendra R. Baliga, MD, FACC, functions in this capacity for JACC and for JACC: Cardiovascular Imaging. He notes that the CME/MOC articles from JACC have been carefully selected to enrich the readers educational experiences with the view of ...

The emerging technology of optogenetics uses optical and genetic means to monitor and modulate the electrophysiological properties of excitable tissues. While transforming the field of neuroscience, the technology has recently gained popularity also in the cardiac arena. Here, we describe the basic principles of optogenetics, the available and evolving optogenetic tools, and the unique potential of this technology for basic and translational cardiac electrophysiology. Specifically, we discuss the ability to control (augment or suppress) the cardiac tissues excitable properties using optogenetic actuators (microbial opsins), which are light-gated ion channels and pumps that can cause light-triggered membrane depolarization or hyperpolarization ...

In-silico models of human cardiac electrophysiology are now being considered for prediction of cardiotoxicity as part of the preclinical assessment phase of all new drugs. We ask the question whether any of the available models are actually fit for this purpose. We tested three models of the human ventricular action potential, the Ohara-Rudy (ORD11), the Grandi-Bers (GB10) and the Ten Tusscher (TT06) models. We extracted clinical QT data for LQTS1 and LQTS2 patients with nonsense mutations that would be predicted to cause 50% loss of function in IKs and IKr respectively. We also obtained clinical QT data for LQTS3 patients. We then used a global optimization approach to improve the existing in silico models so that they reproduced all three clinical data sets more closely. We also examined the effects of adrenergic stimulation in the different LQTS subsets. All models, in their original form, produce markedly different and unrealistic predictions of QT prolongation for LQTS1, 2 and 3. After ...

Definition : Ambulatory electrocardiographs (ECGs) designed for continuous recording of the variations of the electric potential caused by the electrical activity of the heart muscle, usually detected at the body surface typically from three to twelve leads simultaneously. The instrument usually records ECG signals automatically using an electronic storage device (tape recorders may be also used) worn by the patient in which the recording function is always active and includes detachable chest surface electrodes. The recorded signals are analyzed in a processor that includes dedicated software. Also available are ambulatory ECGs that analyze the signal at the time that it is recorded, typically using microprocessors (i.e., real-time recording), and recorders that make the analysis when processing the recorded signal (i.e., retrospective recorders). Continuous ambulatory electrocardiographs are usually worn by the patient for a period of 24 to 48 hours and are used to detect transient cardiac ...

The body sends electrical impulses through the heart that stimulate heartbeats to occur at a consistent rhythm and rate. An electrocardiograph machine can detect and record electrical changes associated with the beating of the heart. Your veterinarian can interpret this information to determine your pets heart rhythm and rate. The process of using the electrocardiograph machine to assess heart rate and rhythm is called electrocardiography, and the result is an electrocardiogram (ECG).. Read More ...

Cardiologist Dr Christian Wolpert, from the University Hospital Mannheim, Germany, (along with Drs Auricchio and Vardas) has researched the current status of cardiac electrophysiology in member countries of the European Society of Cardiology (ESC).. Overall in the emerging economies of ESC member countries, says Dr Wolpert, we have found great disparity in access to anti-arrhythmic therapy, for a variety of reasons. The implant rates and number of treating centres and physicians certainly correlate with the economic status of their countries and budget restrictions. However, even in countries with a higher GDP and where device therapy could be implemented, we have found low awareness, a lack of information and few treating specialist, all of which leads to severe under-treatment. A higher uptake of device therapy could save many sudden cardiac deaths.. An analysis of ICD use in ESC member countries (published by the EHRA in the 2010 White Book)(2) shows a great difference in the number of ...

Theoretical and experimental bases of cardiac electrophysiology and arrhythmias, with particular focus on the role of underlying ionic mechanisms. Theoretical simulations are conducted at both single cell and multicellular tissue and utilize detailed ionic models of the cardiac action potential. Experimental studies involve optically mapping the dynamics of propagation and fibrillation in Langendorff perfused whole hearts. Current focus is on 1. studying the role of an atrial specific ion channel IKur and its usefulness as an antiarrhythmic target in atrial fibrillation, 2. the role of the inward rectifier K+ currents IK1 and IKATP during hyperkalemia and ischemia respectively, in the ventricle.. ...

They say they plan to sterilize the devices, ship them overseas and show that recycling pacemakers is feasible and ethical.. It is our hope with this project to once and for all prove that this is safe and effective therapy for those who cant afford the device, said Dr. Timir Baman, cardiac electrophysiology fellow at the University of Michigan Hospitals and co-founder of Project My Heart ? Your Heart.. The silver-dollar size device is implanted to correct a slow or irregular heart beat which can lead to fatigue or fainting. Depending on how hard the device has to work, it can last up to 10 years.. Baman said the idea for Project My Heart ? Your Heart came from one of his patients who told him she wanted her pacemaker donated for reuse after she died. Baman chuckled at the thought, but she persisted. He looked into it and found that while the FDA forbids the implantation of used pacemakers within the U.S., prohibitions on sending them abroad are fuzzy.. He found that a number of little-known ...
