Electroanatomic Mapping and Catheter Ablation of Breakthroughs From the Right Atrium to the Superior Vena Cava in Patients With Atrial Fibrillation

Abstract
Background— The superior vena cava (SVC) is one of the sources of ectopies that can initiate atrial fibrillation (AF). We investigated by radiofrequency ablation the electrophysiological characteri...
