Prospective randomized trial of transthoracic versus low-energy transvenous internal cardioversion in persistent atrial fibrillation

Abstract

Objective - Electrical cardioversion (CV) is used to restore sinus rhythm (SR) in patients with atrial fibrillation (AF). In this prospective randomized study, we compared two different methods of electrical CV, namely transthoracic (TT) and low-energy transvenous internal CV (ICV), in patients with persistent AF with respect to efficacy, safety and the magnitude of myocardial damage provoked by either method
