Electrophysiological study

Abstract

An electrophysiological (EP) study is performed for diagnostic reasons, for risk assessment, and for therapy of arrhythmias. It can be useful in athletes with palpitations or documented arrhythmias of unclear origin, in non-sustained ventricular tachycardia, structural heart disease, or electrical abnormalities such as the Brugada syndrome, and for treatment of ectopic beats, supraventricular or ventricular tachycardia, and atrial fibrillation.
