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 …

… D and E show magnified intracardiac electrograms of similar duration. It is evident in panel E
that … The morphology of the tachycardia in panel E is wider than the morphology in panel D. …

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 …
