Accelerated Idioventricular Rhythm
A type of automatic, not reentrant, ectopic ventricular rhythm with episodes lasting from a few seconds to a minute which usually occurs in patients with acute myocardial infarction or with DIGITALIS toxicity. The ventricular rate is faster than normal but slower than tachycardia, with an upper limit of 100 -120 beats per minute. Suppressive therapy is rarely necessary.
Cardiac Complexes, Premature
A group of cardiac arrhythmias in which the cardiac contractions are not initiated at the SINOATRIAL NODE. They include both atrial and ventricular premature beats, and are also known as extra or ectopic heartbeats. Their frequency is increased in heart diseases.
Tachycardia
Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.
Arrhythmias, Cardiac
Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.
Electrocardiography
Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.
Chlorpheniramine
A histamine H1 antagonist used in allergic reactions, hay fever, rhinitis, urticaria, and asthma. It has also been used in veterinary applications. One of the most widely used of the classical antihistaminics, it generally causes less drowsiness and sedation than PROMETHAZINE.
Heart Ventricles
The lower right and left chambers of the heart. The right ventricle pumps venous BLOOD into the LUNGS and the left ventricle pumps oxygenated blood into the systemic arterial circulation.
Heart Block
Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
Methylhistamines
Histamine substituted in any position with one or more methyl groups. Many of these are agonists for the H1, H2, or both histamine receptors.
Heart Rate
The number of times the HEART VENTRICLES contract per unit of time, usually per minute.
Circadian Rhythm
The regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, and feeding.
Myocardial Infarction
NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).

Antitachycardia burst pacing for pleomorphic reentrant ventricular tachycardias associated with non-coronary artery diseases: a morphology specific programming for ventricular tachycardias. (1/8)

To study the role of antitachycardia burst pacing in patients with reentrant pleomorphic ventricular tachycardia (VT) associated with non-coronary artery diseases, the efficacy of antitachycardia pacing and appropriate antitachycardia pacing cycle length were evaluated in each pleomorphic VT morphology of seven patients. Seven patients were included in this study. Clinically documented pleomorphic VTs were reproduced in an electrophysiologic study. For each VT, rapid ventricular pacing was attempted from the apex of the right ventricle at a cycle length which was 20 ms shorter than that of VT and repeated after a decrement of the cycle length in steps of 10 ms until the VT was terminated or accelerated. All 16 VTs could be entrained by the rapid pacing, and 13 of the 16 VTs (81%) were terminated, whereas pacing-induced acceleration was observed in the other 3 VTs of the 3 patients. VT cycle length (VTCL), block cycle length (BCL) which was defined as the longest VT interrupting paced cycle length, %BCL/VTCL and entrainment zone which was defined as VTCL minus BCL, varied in each VT morphology of each patient. In two patients, antitachycardia pacing was effective in all VT morphologies and the maximum difference of the %BCL/VTCL among the pleomorphic VTs was less than 10%. Thus, antitachycardia pacing seemed to be beneficial for these patients. In the other 5 patients, a difference of more than 10% in %BCL/VTCL was observed among the pleomorphic VT morphologies and/or at least one VT morphology showed pacing-induced acceleration. Compared to the 13 terminated VTs, three accelerated VTs had a wide entrainment zone [160 +/- 44 vs 90 +/- 48 ms, p < 0.04] and small %BCL/VTCL [61 +/- 6 vs 77 +/- 11%,p<0.03]. In pleomorphic VTs associated with non-coronary artery diseases, responses to rapid pacing was not uniform; VT might be terminable or accelerated even in the same patient. We need to pay close attention when programming antitachycardia pacing in patients with pleomorphic VT.  (+info)

The D allele of the angiotensin-converting enzyme gene and reperfusion-induced ventricular arrhythmias in patients with acute myocardial infarction. (2/8)

The renin-angiotensin system may play a pivotal role in reperfusion ventricular arrhythmias (RVA). The purpose of this study was to investigate the association between angiotensin-converting enzyme (ACE) gene polymorphism and RVA in patients with acute myocardial infarction (AMI) in a case-control study. Patients who had undergone successful coronary intervention for AMI were enrolled (n= 127, male/female: 97/30, mean age, 62.6 years). The incidence of RVA was continuously monitored by ECG at a coronary care unit. The severity of ventricular arrhythmias was evaluated in terms of the Lown's grade and patients with a high risk of ventricular arrhythmias that may cause sudden cardiac death (Lown's grade > or =2) within 5 h of coronary intervention were defined as cases (n=59), and otherwise as controls (n=68). A receiver operating characteristic curve was used to determine the discriminatory ability of continuous variables and to produce dummy variables for use in a logistic regression analysis. Cases had a significantly higher body mass index, higher maximal levels of serum creatine kinase, and a shorter time preceding coronary intervention than controls. The severity of coronary atherosclerosis was similar between the 2 groups. The frequency distribution of ACE genotypes in cases differed from that in controls (II/ID/DD: 22.0%/52.6%/25.4% vs 44.1%/41.4%/14.7%, p<0.05, by the Mantel-Haenzel chi-square test). The ACE-D allele had additive and dominant effects with regard to the occurrence of significant ventricular arrhythmias after adjusting for other risk factors. The ACE-D allele may play a pivotal role in sudden cardiac death in patients with AMI.  (+info)

Five cases of aconite poisoning: toxicokinetics of aconitines. (3/8)

Aconite poisoning was examined in five patients (four males and one female) aged 49 to 78 years old. The electrocardiogram findings were as follows: ventricular tachycardia and ventricular fibrillation in case 1, premature ventricular contraction and accelerated idioventricular rhythm in case 2, AIVR in case 3, and nonsustained ventricular tachycardia in cases 4 and 5. The patient in case 1 was given percutaneous cardiopulmonary support because of unstable hemodynamics, whereas the other patients were treated with fluid replacement and antiarrhythmic agents. The main aconitine alkaloid in each patient had a half-life that ranged from 5.8 to 15.4 h over the five cases, and other detected alkaloids had half-lives similar to the half-life of the main alkaloid in each case. The half-life of the main alkaloid in case 1 was about twice as long as the half-lives in the other cases, and high values for the area under the blood concentration-time curve and the mean residence time were only observed in case 1. These results suggest that alkaloid toxicokinetics parameters may reflect the severity of toxic symptoms in aconite poisoning.  (+info)

Electrophysiological study and 'slow' ventricular tachycardia predict appropriate therapy: results from a single-centre implantable cardiac defibrillator follow-up. (4/8)

AIMS: To account for appropriate and inappropriate therapies and cardiac death (CD) in a cohort of consecutive implantable cardiac defibrillator (ICD) eligible patients and to identify baseline predictors of these outcomes. METHODS AND RESULTS: During follow-up of 288 consecutive ICD-treated patients, clinical, biochemical, echocardiographic, arteriographic, and electrophysiological (EP) data at baseline were individually matched with survival data and electrograms retrieved during device interrogation. Predictors of therapy and CD were identified by multivariate analyses. Eighty-eight per cent of cases were secondary prevention and 12% were primary prevention. About 770 patient-years of ICD follow-up were analysed. Median follow-up was 22.7 months. Forty-eight per cent of patients had appropriate therapy for at least one ventricular tachyarrhythmia. Seventy per cent of tachycardias were successfully treated with anti-tachy pacing alone. Overall risk of therapy was higher for patients with ischaemic heart disease (IHD) than with non-IHD (51 vs. 37%; P = 0.049). Low left ventricular ejection fraction (LVEF), positive EP study, and 'slow' ventricular tachycardia predicted appropriate therapy. Cardiac death was predicted by nephropathy, low LVEF, amiodarone use, and supraventricular tachycardia (SVT). Inappropriate therapy affected 12.2% of patients and was predicted by known SVT and IHD. CONCLUSION: Electrophysiological study and slow VT predicted appropriate therapy. Amiodarone use predicted CD. Inappropriate therapy remains an important issue largely predictable by SVT.  (+info)

Reentrant ventricular tachycardia originating in the right ventricular outflow tract: slow conduction identified by right coronary artery ostium pacing. (5/8)

A case of reentrant ventricular tachycardia (VT) originating from the right ventricular outflow tract (RVOT) is described. An electrophysiological study revealed that programmed stimulation from the right ventricle apex induced 2 types of VT with similar left bundle branch block configuration and inferior axis. Yet, VT cycle length (CL) was different; one was stable, sustained VT with a CL of 360 ms and the other was hemodynamically intolerable VT with a CL of 330 ms. Similarly for both VTs, perfect pace mapping was obtained at the anterior septum beneath the pulmonary valve in the RVOT, and exits of both VTs were very close. Entrainment mapping during stable VT was performed and the anterior septum RVOT was designated as the exit for the stable VT. Intriguingly, entrainment pacing from the ostium of the right coronary artery showed that the post-pacing interval was identical to VTCL. The stimulus to QRS interval was very long (340 ms) during entrainment with concealed fusion, and the right coronary artery ostium was therefore consistent with the VT reentry circuit inner loop or the upper portion of the VT reentry circuit exit. These findings suggest that the stable VT reentry circuit had a slow conduction zone from the ostium of the right coronary artery to the exit in the anterior septum RVOT. When radiofrequency catheter ablation was performed at the 2 exits of the anterior septum RVOT, both VTs then could not be induced.  (+info)

More pronounced diastolic left ventricular dysfunction in patients with accelerated idioventricular rhythm after reperfusion by primary percutaneous coronary intervention. (6/8)

OBJECTIVE: Reperfusion-induced accelerated idioventricular rhythm (AIVR) during primary percutaneous coronary intervention (pPCI) may be a sign of left ventricular (LV) dysfunction. We compared LV dynamic effects of reperfusion between patients with and without reperfusion-induced AIVR during pPCI for ST-elevation myocardial infarction (STEMI). METHODS: We studied 15 consecutive patients, who presented with their first acute anterior STEMI within 6 hours after onset of symptoms, and in whom LV pressure-volume (PV) loops were directly obtained during pPCI. Immediate effects of pPCI on LV function were compared between patients with (n = 5) and without (n = 10) occurrence of AIVR after reperfusion, as well as the direct effects of AIVR on LV function compared to sinus rhythm. RESULTS: Patients with reperfusion-induced AIVR showed more pronounced diastolic LV dysfunction before the onset of the arrhythmia, i.e., a delayed active relaxation expressed by Tau (53 +/- 15 vs. 39 +/- 6 ms; p = 0.03), a worse compliance curve (p = 0.01), and a higher end-diastolic stiffness (p = 0.07). At the end of the procedure, AIVR patients showed less improvement in diastolic LV function, indicated by a downward shift of the compliance curve (-3.1 +/- 2.3 vs. -7.5 +/- 1.4 mmHg; p = 0.001), a decrease in end-diastolic stiffness (13 +/- 18 vs. 34 +/- 15%; p = 0.03) and end-diastolic pressure (12 +/- 8 vs. 29 +/- 19%; p = 0.07). CONCLUSION: STEMI patients with reperfusion-induced AIVR after pPCI showed more pronounced diastolic LV dysfunction before and after AIVR than patients without AIVR, which suggests that diastolic LV dysfunction contributes to the occurrence of AIVR and that AIVR is a sign of diastolic LV dysfunction.  (+info)

Accelerated idioventricular rhythm associated with propranolol treatment in a child. (8/8)

Accelerated idioventricular rhythm (AIVR) is a ventricular arrhythmia most commonly seen in adults with underlying cardiac disease. It is important to establish the diagnosis when it occurs to differentiate this benign phenomenon from dangerous ventricular tachycardia. We present the case of a healthy child who developed episodes of AIVR associated with propranolol treatment. Her 24-hour electrocardiography recording showed AIVR with difference between sinus and ventricular beats. The arrhythmia resolved with the discontinuation of propranolol, and eventually the case was in sinus rhythm. This patient is the first case of AIVR associated with propranolol treatment in the literature.  (+info)

FOXY MAMMALS RESCUE BRIAN ENOS LEGACY WITH THEIR NEW SINGLE SLOW | Indie-Music.comFOXY MAMMALS RESCUE BRIAN ENOS LEGACY WITH THEIR NEW SINGLE SLOW | Indie-Music.com
Foxy Mammals announce the release date for their new single ´Slow´-on September the 4th. This new song, which moves between blues and rock, has been mixed and mastered at Forking Path Studios, in a place called Tujunga -up from the foothills of Los Angeles National Forest (USA)- by the grammy-nominated engineer Nick Page.. As Brian Eno did in 1995 by publishing the album Original Soundtracks 1, the composition of ´Slow´ is thought of as if it were a soundtrack to a movie. The main plot of the film would deal with the feelings of loss of childhood, the purity of love in those early years, and the later inner struggle to maintain innocence.. After the halt, forced worldwide by covid-19, the band Foxy Mammals continue its schedule of concerts and activities which will lead them to enter the studio again at the end of this year..

Capacitor for an implantable cardiac defibrillator - Patent # 5983472 - PatentGenius
A method of manufacturing a capacitor for use in an implantable cardiac defibrillator by forming a set of conductive sheets with the same profile having a sacrificial portion. An alignment figure is formed in each sheet, and the sheets are stacked and aligned by registering the alignment figures with each other. The sacrificial portions are removed from each of the sheets, which are secured together and positioned in a capacitor housing. Each sheet may include two major portions joined by the sacrificial portion, so that each major portion may become part of a separate capacitor stack after the sacrificial portion is removed, doubling manufacturing throughput.

In a fly, butterfly, locust and dragonfly we examined the responses of a variety of directional motionsensitive neurons which run from the brain down the ventral cord. The stimulus was a sinusoidally modulated moving pattern of regular stripes presented at a range of velocities in random order for either 0.1 s or 2.0 s. The response was measured as the total number of spikes to each stimulus. The neurons fall into two groups, fast and slow. The responses of the fast type rise progressively to a peak contrast frequency at 15-20 Hz for all four insects, and decline at higher contrast frequencies. The responses of slow neurons rise rapidly to a peak at 1-10 Hz and then decline more slowly across the range where the fast neurons are at their peak. The existence of two groups of neurons with overlapping response ranges to different velocities of the same pattern, presented in exactly the same way, provides the insect with a means of measuring angular velocity irrespective of contrast, spatial ...

The AV is a semilunar valve with three cusps located close to the center of the heart. The aortic root is not a specific structure, per se, but includes the AV annulus, cusps, sinuses of Valsalva, coronary artery ostia, sinotubular junction, and proximal ascending aorta. The LVOT is the outflow portion of the LV just inferior to the AV. All these structures are examined in detail with TEE by using four cross-sections.. The mid esophageal AV short axis view (Figure 3h) is obtained from the mid esophageal window by advancing or withdrawing the probe until the AV comes into view and then turning the probe to center the AV in the display. The image depth is adjusted to between 10 and 12 cm to position the AV in the middle of the display. Next, the multiplane angle is rotated forward to approximately 30 to 60 degrees until a symmetrical image of all three cusps of the aortic valve comes into view. This cross-section is the only view that provides a simultaneous image of all three cusps of the AV. The ...

Non-Equilibrium Phenomena in Soft Matter | Max Planck Institute for Polymer ResearchNon-Equilibrium Phenomena in Soft Matter | Max Planck Institute for Polymer Research
Progress in experimental and advanced computational modeling methodologies, now allows the observation of (supra-) molecular structural evolution across the wide range of length- and time scales, which is necessary to comprehend, and ultimately control and manipulate, the macroscopic (functional) properties of soft matter at the molecular level. Soft matter is particularly suited for that approach, as it is slow and easy to manipulate. From the experimental point of view, non-equilibrium states can be tuned through the material processing (e.g. crystallization in confined geometries, electrospinning, etc.). On this track at MPI-P a whole range of projects contribute to this development. Template guided synthesis on superamphiphobic surfaces, able to repel any kind of liquid, allows to create core-shell supraparticles induced by drying of a solution containing two different kinds of nanoparticles. Or a superamphiphobic substrate can be used to guide the assembly of superparamagnetic (a kind of ...

Myocarditis is simply inflammation of the heart muscle. The etiology is varied and may be secondary to a variety of infections, systemic diseases, drugs, and toxins, Viral myocarditis is usually self limited but can lead to chronic dilated cardiomyopathy and sudden cardiac death. Patients often present with chest pain, elevated cardiac enzyme levels, and ECG changes, making differentiation from acute infarction difficult. On contrast enhanced MRI, the presence of focal delayed enhancement in a non-coronary artery distribution together with wall motion abnormalities correlates strongly with acute or subacute myocarditis. The enhancement becomes less intense and more diffuse over time. Myocarditis lesions occur predominantly in the lateral free wall. Contrast enhancement does not typically affect the subendocardium like infarction. Myocardial necrosis of myocarditis is also usually less confluent than infarction.. ...

AWR Technology Sidereal Clock
OPERATION The time is set through the serial port from LX200 devices or through the keyboard using the SET key in conjunction with FAST or SLOW. The hours is set first, then the minutes. The seconds display is zeroed when the minute is incremented during set so to synchronise the time (using the telephone time service, for example) the minute counter must be advanced exactly on the minute pip. With practise the setting error can be made less than 0.2 seconds, and of course it can be checked at the next time check and re-done if necessary. Automatically calculating the sidereal time once the UT time is set is not easy. You require the LONGITUDE of your place on the earth and the DATE and YEAR. There is no way this information can be input into the clock. The metronome is available at any time by pressing the switch, pressing it again to turn it off. This will cause short beeps at every second with a longer beep at the minute. The start of the sound is always in synchronism with the UT ...

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]). ...

The primary objective is to establish the role of genetics in life-threatening arrhythmias leading to sudden cardiac death (SCD) and the potential utility of genetic markers in risk stratification of patients to receive an implantable cardiac defibrillator (ICD). The successful accomplishment of this goal would serve as the basis for future work on a specific diagnostic test that can be used to assess risks of threatening arrhythmias in order to quality patients for implantation of an ICD.. ...

Figure 3: Follow up electrocardiogram demonstrating frequent ventricular ectopy. Conclusion: Sawtooth cardiomyopathy had been previously proposed as the diagnosis based on the patients prior invasive study. Disordered cardiac embryogenesis was also suspected. To date the patient has not received any therapies from his implantable cardiac defibrillator. Perspective: While similar morphology has been previously described, underlying mechanisms of this unusual form of myocardial disease remains unknown.1 Further investigations that would be potentially informative, such as genetic testing and endomyocardial biopsy with precise characterization of ultrastructural abnormalities have not been pursued at this time.2.

CTEPH should be considered in all patients with unexplained PH and the first step in diagnosis should be obtaining the patients medical history. Pulmonary embolism is the most common cause of CTEPH. Although it was previously estimated that up to 63% of patients with CTEPH have no history of acute pulmonary embolism [2], recent data from an international prospective registry of patients with newly diagnosed CTEPH suggest a much lower value. Previous pulmonary embolism was confirmed for 74.8% of patients and deep-vein thrombosis in 56.1% [5], which is in line with findings from other recent studies [4]. Other risk factors that may suggest the presence of CTEPH include ventriculo-atrial shunt, indwelling catheters and leads (such as chronic dialysis catheters and pacemakers or automated implantable cardiac defibrillator leads), splenectomy, thyroid replacement therapy, inflammatory bowel disease and a history of malignancy [7, 8].. Obtaining the patients history should be followed by physical ...

Tammy, please take heart and please, please give yourself some time to recover. It is amazing how the brain can recover from things. After my sons last chemo treatment, he was so ill. He had serious brain edema...a lot of swelling. This is how bad he was: he was in diapers. He could not talk, could not say his name, could not feed himself, could not walk. He was sitting and drooling. He would stare off into space and it seemed like he was not aware we were in the room. He would do purposeless random repetitive motions like tapping or rocking. I thought his life as it had been was over...that our David was lost to us. He was like a stranger to us.. Well, he recovered, Tammy. He came back from all of that. He is back just about 100%. He still has quite a bit of fatigue and hes pretty weak, but thats improving too. Its unbelievable. The doctors said thats what brain swelling will do to you. I dont know if you have issues with swelling but that could be part of your problem since its common ...

I played with a Casio fx9860 today
im fairly pleased with the CPU performace of the 50g for my cross developments and regard it as a hardware platform. when using hpgcc, im switching off the slow mode to get the full speed. presumably the slow mode is also off for normal use - or is the machine underclocked by default. if so that could be interesting.. i suspect that HP would have used a slower processor if they hadnt needed the saturn emulation. so from their point of view, the use of a 75MHz ARM9 was an unavoidable mistake. i have always thought that hp calculators were too slow. this time around, i see the mistake as an advantage in that the calculator is, at last, not too slow and can actually do some really interesting stuff. more ram would be useful too :-) hopefully hp will begin see their mistake as an asset and intentionally posit cheap/low power and fast cpus.. i agree that the 35s is too slow, embarrassingly underperforming its predecessors in some tests. this has let down, otherwise, quite a nice calculator. ...

Lithium cells, if ingested, are highly dangerous. In the pediatric population, of particular concern is the potential for one of these batteries to get stuck in the oesophagus.[11][12] Such impactions can rapidly devolve and cause severe tissue injury in as little as two hours.[12][17][18] The damage is not caused by the contents of the battery, but by the electric current that is created when the anode (negative) face of the battery comes in contact with the electrolyte-rich esophageal tissue. The surrounding water undergoes a hydrolysis reaction that produces a sodium hydroxide (caustic soda) build-up near the batterys anode face (cathodic reaction in the electrolyte). This results in the liquefactive necrosis of the tissue, a process whereby the tissue effectively is melted away by the alkaline solution.[17] Severe complications can occur, such as erosion into nearby structures like the trachea or major blood vessels, the latter of which can cause fatal bleeds. While the only cure for an ...

Not to get all science-y on you, but you want some beta oxidation in your life. Beta oxidation is when your body is using its fatty acid molecules (aka burning fat). This is the slow burn youve always heard about. Your body is in a beta oxidation state when you are in low-intensity cardiovascular (aerobic) activity. This doesnt burn as many calories as quickly as anaerobic (like HIIT) workouts, but there needs to be both in your weekly routine. I dont know about you, but I like it when I know my body is using its fatty acid (aka fat storage) immediately, even if its a longer workout.

CARG: Coronary Artery Rehabilitation Group Blog: New defibrillator works without wires touching heartCARG: Coronary Artery Rehabilitation Group Blog: New defibrillator works without wires touching heart
A new implantable defibrillator accurately detects abnormal heart rhythms and shocks the heart back into normal rhythm, yet has no wires touching the heart, new research shows. The device, called a subcutaneous implantable cardiac defibrillator (S-ICD), is placed under the patients skin and has a wire under the skin along the left side of the breast bone. The device detects life-threatening arrhythmias from normal rhythms, and once it notices the life-threatening rhythm it will automatically shock the heart back to its normal rhythm, said lead researcher Dr. Martin Burke, director of the Heart Rhythm Center at the University of Chicago. The advantage of the device is its durability - it lasts longer because there is not as much flexibility in the wiring, Burke said. Wires in standard implantable defibrillators need to be flexible to pass through blood vessels to the heart. This makes the system enticing for younger patients who have risk of cardiac arrest who currently dont get standard ...

Most patients with chronic ischemia and an implantable cardiac defibrillator (ICD) for primary prevention do not experience therapies for ventricular arrhythmias on follow-up. The present study aimed to identify independent clinical, electrocardiographic, and echocardiographic predictors of death and occurrence of ICD therapy in patients with chronic ischemic cardiomyopathy and ICD for primary prevention. A total of 424 patients with chronic ischemic cardiomyopathy, ejection fraction ≤35%, and New York Heart Association (NYHA) class ,0.001) predicted the occurrence of ICD therapy on follow-up. In conclusion, in chronic ischemic patients with an ICD for primary prevention, the presence of diabetes, renal dysfunction, higher NYHA class, and impaired peri-infarct zone function were predictors of all-cause mortality. In contrast, only impaired peri-infarct zone function determined the occurrence of appropriate ICD therapy on follow-up.. ...

We offer the full breadth of the most advanced, leading-edge protocols for the diagnosis and treatment of cardiac rhythm abnormalities, also known as arrhythmias. These include device therapies, invasive EP studies and interventional electrophysiology.. Device-based treatments include pacemakers for slow rhythms, implantable cardiac defibrillators (ICDs) for abnormally fast rhythms that can result in sudden death, and cardiac resynchronization therapy (biventricular devices) for advanced heart failure.. Interventional electrophysiology utilizes radiofrequency energy (heat) or cryotherapy (cold) to selectively ablate or eliminate the source or the structures critical for an arrhythmia to perpetuate. The target for ablation can be pinpointed with an invasive EP study, where electrode catheters are strategically placed in the heart, permitting precise mapping of an arrhythmia..

In life and in Cannells world of music, hitting the high notes often takes hard work. Three years after being diagnosed with cardiomyopathy, Cannells best option for living was a heart transplant.. I had no family history of heart disease and I found myself in need of a new heart, says Cannell, of Saline, Mich., a husband and father of three. I dealt with it all with great support and humor whenever we could.. The scariest part was hearing during the transplant evaluation that I had end stage heart failure.

Hugo Campos is a proponent of this movement: He uses aFitBit device to keep track of his daily activity level, a Withings blood pressure monitor, a WiFi scale, and a Zeo sleep monitor. He cannot, however, access the data in his implantable cardiac defibrillator (ICD) because such data is off limit to patients. The data from his ICD can, however, be accessed by his physician and the devices manufacturer.. In his quest to learn about his condition and ICDs, Campos attends cardiology conferences, takes classes on how to program ICDs, and does everything [he] can to raise [his] own level of health literacy, as he explained in a recent TEDx talk. He firmly supports the e-patient movement, in which networked patients are shifting from being just mere passengers to becoming responsible drivers of their care..

Heart attack - A heart attack occurs when the blood supply to part of the heart muscle itself - the myocardium - is severely reduced or stopped. The reduction or stoppage happens when one or more of the coronary arteries supplying blood to the heart muscle is blocked. This is usually caused by the buildup of plaque (deposits of fat-like substances), a process called atherosclerosis. The plaque can eventually burst, tear or rupture, creating a snag where a blood clot forms and blocks the artery. This leads to a heart attack ...

Antibiotic rotation has been previously studied with varied results. The theory behind antibiotic rotation is that intermittently changing antibiotic classes will reduce the ecological selective pressure that drives the emergence of antibiotic resistance.. This study compares the effect of 2 types of antibiotic rotation on Gram-negative colonisation in the ICU and also compares both interventions with standard care.. The two interventions apply to the empiric treatment and are: 1) fast rotation, i.e. every other patient another class and 2) slow rotation, i.e. every other 1.5month another preferred class for empiric Gram-negative antibiotic therapy. ...

AIVR13
  • Accelerated idioventricular rhythm (AIVR) is diagnosed based on its characteristic electrocardiography findings. (medscape.com)
  • AIVR is a wide QRS ventricular rhythm with rate of 40-120 bpm, often with variability during the episode. (medscape.com)
  • AIVR and sinus rhythm: AIVR starts and terminates gradually, competing with sinus rhythm. (medscape.com)
  • AIVR has a wide QRS morphology different from the QRS morphology in sinus rhythm. (medscape.com)
  • AIVR can occur in atrial fibrillation (see image below) and other rhythms when the rate of firing in ectopic ventricular focus surpasses that of the underlying dominant ventricular rate. (medscape.com)
  • Unlike junctional/accelerated junctional rhythm , AIVR has a wide QRS morphology that is different from the narrow QRS morphology in sinus rhythm without aberrancy and the wide QRS morphology with typical bundle branch block patterns. (medscape.com)
  • Occasionally, AIVR may be the patient's only rhythm. (medscape.com)
  • History is helpful for identifying the underlying etiology for accelerated idioventricular rhythm (AIVR). (medscape.com)
  • There are no specific physical findings for accelerated idioventricular rhythm (AIVR). (medscape.com)
  • Some irregularity of heart rate/pulse rate due to competing sinus rhythm and AIVR. (medscape.com)

(drugs.com)
  • Sinus rhythm, nearly tachycardia. (blogspot.com)
  • The heart rate is 50-120 bpm, which is faster than a ventricular rhythm but slower than ventricular tachycardia. (practicalclinicalskills.com)
  • Given that 80% of wide complex rhythms are Ventricular Tachycardia(VT), we can settle on that for most patients. (cardiacbootcamp.org)
  • Therefore, this is an accelerated idioventricular rhythm (or idioventricular tachycardia), an arrhythmia due to an enhanced and unprotected ectopic ventricular pacemaker [1] with a rate between 50 and 120 beats per minutes (bpm), then faster than normal intrinsic ventricular escape rhythm, but slower than ventricular tachycardia, that is also influenced by sinus pacemaker, unlike parasystole. (juniperpublishers.com)
Arrhythmias2

Slow1
  • Members can go to the ' Narrow Complex Tachycardias' section to view my simple algorithm approach to the fast and slow rhythms. (cardiacbootcamp.org)
Diagnosis1
  • The peculiarity of this ECG, that makes the diagnosis challenging, is the irregularity of the rhythm, since regularity of R-R intervals is considered to be one of the diagnostic criteria of idioventricular rhythms [3]. (juniperpublishers.com)
Beat1
