背景资料：肺静脉窦隔离术（PVAI）后房颤（ERAF）的早期复发很常见;然而，既往研究中的定义、研究人群和病变集并不统一。我们检查ERAF阵发性AF，同时符合最新guidelines.Methods和Results中的定义：我们纳入了471例经验性PVAI阵发性AF的患者。ERAF在180例（38.2%）中观察到，包括49，16和115在3，4-7天，8-90天，分别在索引程序后。ERAF（风险比6.872; 95%置信区间4.803-9.382; P
Background: Early recurrence of atrial fibrillation (ERAF) is common after pulmonary vein antrum isolation (PVAI); however, the definition, study population, and lesion set are not uniform in prior studies. We examined ERAF for paroxysmal AF while complying with the definition in the latest guidelines.Methods and Results: We included 471 patients undergoing empirical PVAI for paroxysmal AF. ERAF was observed in 180 patients (38.2%) including 49, 16, and 115 within 3, 4-7 days, and 8-90 days, respectively, after the index procedure. ERAF (hazard ratio 6.872; 95% confidence interval 4.803-9.382; P
