Our objective was to establish a novel model for the study of ventricular fibrillation (VF) in
humans. We adopted the established techniques of optical mapping to human ventricles for the …

Ventricular fibrillation (VF) is an important cause of sudden cardiac death and cardiovascular
mortality in patients with cardiomyopathy. Although it was generally believed that chaotic …

Objectives. Four patients with previous repair of tetralogy of Fallot and ventricular tachycardia
underwent map-guided surgery to ablate the arrhythmias. Background. Although patients …

Objectives : The purpose of this study was to evaluate the cardiac consequences of
neuromuscular incapacitating device (NID)/stun gun discharge in an experimental model. …

Objective.The purpose of this study was to obtain improved detection and characterization of
reentrant circuits in the n-farcted human ventricle. Background. The return path of reentrant …

The ability of an electrical discharge to stimulate the heart depends on the duration of the
pulse, the voltage and the current density that reaches the heart. Stun guns deliver very short …

Objectives. This study was conducted to characterized the functional nature of the reentrant
tract responsible for ventricular tachycardia due to ischemic heart disease. Background. A …

BACKGROUND: Complex fractionated atrial electrograms have been suggested as important
targets for catheter ablation of atrial fibrillation. The etiology and the mechanism of these …

The effect of lack of global coronary perfusion on myocardial activation rate, wavebreak, and
its temporal progression during human ventricular fibrillation (VF) is not known. We tested …

Ventricular fibrillation (VF) is a medical condition that occurs due to rapid and irregular electrical
activity of heart. If undiagnosed or untreated, VF leads to sudden cardiac death. VF has …
