A Comparison of Electrophysiologically Guided Antiarrhythmic Drug Therapy with Beta-Blocker Therapy in Patients with Symptomatic, Sustained Ventricular Tachyarrhythmias

Abstract

As compared with metoprolol therapy, electrophysiologically guided antiarrhythmic drug therapy did not improve the overall outcome of patients with sustained ventricular tachyarrhythmias. However, effective suppression of inducible arrhythmia by antiarrhythmic drugs was associated with a better outcome than was lack of suppression.
