Decremental Pulmonary Venous Pulse Propagation: Impact for Catheter Ablation in Focal Atrial Fibrillation

Abstract

Background: Electrical isolation of pulmonary veins (PV's) is crucial to achieve success in catheter ablation for trigger elimination in focal atrial fibrillation (AF). To guide ostial PV radiofrequency (RF) delivery, it is necessary to identify the electrical breakthrough (EBT) between PV and left atrium. For this purpose, coronary sinus (CS) fixed rate… (More)
