title: Indications for electrophysiologic study in patients with ventricular arrhythmias.
abstract: Electrophysiologic study provides valuable information in the management of patients with known or suspected ventricular tachyarrhythmias. It should be used when there is uncertainty about the origin of a wide QRS tachycardia. It is useful in evaluating heart disease patients with unexplained syncope and in stratifying prognosis and guiding therapy in patients with malignant ventricular arrhythmias. All patients being considered for treatment of ventricular tachyarrhythmias with an electrical device should undergo thorough electrophysiologic study. Electrophysiologic study is also indispensable in guiding ablative therapy in patients with drug-refractory malignant ventricular arrhythmias.
