Electrophysiological Mechanisms of Spontaneous Termination of Sustained Monomorphic Reentrant Ventricular Tachycardia in the Canine Postinfarction Heart

Abstract

Distinct electrophysiological changes always preceded spontaneous termination of stable SMVT. The electrophysiological basis for acceleration of conduction in parts of the reentrant circuit during the last few beats prior to termination and of the abrupt reactivation across a stable arc of block remains to be determined.
