Bi-directional electrical pulmonary vein isolation as an endpoint for ablation of paroxysmal atrial fibrillation

摘要

ObjectiveVarious approaches to pulmonary vein (PV) isolation have shown variable efficacy in patients with paroxysmal atrial fibrillation (AF). The purpose of this study is to report the efficacy and safety of routine isolation of all PVs using an endpoint of bi-directional electrical block.
