Mechanisms for spontaneous termination of monomorphic, sustained ventricular tachycardia: results of activation mapping of reentrant circuits in the epicardial border zone of subacute canine infarcts.

Abstract

OBJECTIVES The objective of this study was to determine why sustained ventricular tachycardias (VT) sometimes stop without outside intervention. BACKGROUND Sustained, monomorphic VT in patients with ischemic heart disease is often caused by reentrant excitation. These tachycardias can degenerate into rapid polymorphic rhythms or occasionally terminate… (More)
