Numerous factors can contribute to sudden cardiac death, from underlying disease after myocardial infarction to genetic variants that can claim young lives. In 'Bedside to Bench', Stanley Nattel ...

Ventricular repolarization (VR) is a crucial step in cardiac electrical activity because it corresponds to a recovery period setting the stage for the next heart contraction. Small perturbations of ...

The first ever genetically modified porcine-to-human cardiac xenotransplant, providing new insight into a novel and evolving field. The first ever genetically modified porcine-to-human cardiac ...

Early repolarization is a common finding in young, healthy individuals. It appears as mild ST segment elevation that can be diffuse; however, it is more prominent in the precordial leads. The ST ...

Background:Epidemiological data suggest increased risk of sudden death during and immediately after hemodialysis. Microvolt T-wave alternans (mTWA) is an electrocardiogram (ECG) measure of abnormal ...

SAN FRANCISCO -- Cardiac repolarization dynamics seemed to cycle in sync with the menstrual cycle of some people with congenital and drug-induced long QT syndrome (LQTS), a small prospective study ...

An arrhythmia (also termed cardiac dysrhythmia) is described as an irregular heartbeat caused by aberrant electrical activity in the heart. There are multiple categories of arrhythmia, each of which ...
