Multiple monophasic shocks improve electrotherapy of ventricular tachycardia in a rabbit model of chronic infarction.

BACKGROUND We previously showed that the cardioversion threshold (CVT) for ventricular tachycardia (VT) is phase dependent when a single monophasic shock (1MP) is used. OBJECTIVE The purpose of this study was to extend these findings to a biphasic shock (1BP) and to compare the efficacy of phase-independent multiple monophasic (5MP) and biphasic shocks… (More)
