The invention relates to the use of zucapsaicin (cis-8-methly-N-vanillly-6-nonenamide), the cis-isomer of capsaicin, to treat myocardial disorders, including the prevention, suppression or reversal of an abnormal cardiac rhythm, such as ventricular tachycardia. In vitro, zucapsaicin exhibits electrophysiologic properties distinct from capsaicin. In contrast to capsaicin, zucapsaicin significantly shortens the action potential duration at a dose of 10.sup.-5 M and has no effect on the amplitude of Phase 1 of the action potential in normal Purkinje cells. Zucapsaicin also prevents the induction of ventricular tachycardia of focal Purkinje origin when given intravenously after coronary occlusion in a dog model of acute myocardial infarction.
