Background—The mechanism by which biphasic waveforms improve defibrillation efficacy is unclear. In addition, the optimal shape of the biphasic waveforms remains controversial. Animal experiments ...

BACKGROUND: Penetrance and risk of ventricular arrhythmias (VAs) in arrhythmogenic right ventricular cardiomyopathy (ARVC) are increasingly recognized as being genotype specific. Therefore, ...

Background and objective Prior studies have suggested that patients with premature ventricular complexes (PVCs) may have an ...

A cardiologist at Bassett Medical Center in Cooperstown has become one of the first in the area to implant a device designed to help patients with tachycardia.

Many people who have suffered a heart attack subsequently develop life-threatening complications like ventricular fibrillation. Now an international research team from the University of Freiburg's ...

Researchers have developed a novel method for simultaneously recording action potentials (APs)—temporary changes in ...

Historical records contain evidence of biphasic sleeping habits in humans dating back hundreds of years. According to Ekirch, sleep in preindustrial western civilizations happened in two shifts.

Responding to MAUDE data, some have safety concerns but others aren’t surprised to see more events in higher-risk patients.

Ventricular tachycardia, ventricular fibrillation or ventricular flutter occurred in 9 patients receiving carvedilol (0.9%) and 38 patients receiving placebo (3.9%), respectively (P <0.0001).

Differentiating between ventricular tachycardia and ventricular fibrillation in clinical and preclinical research is based on subjective definitions that have yet to be validated using objective ...
