目的探讨心房颤动（简称房颤）环肺静脉消融术（CPVA）后复发的预测因素。
Objective To determine the predictors of recurrence of atrial tachyarrhythmias(ATa) after circumferential pulmonary vein ablation (CPVA) for patients with atrial fibrillation(AF).
对于阵发性房颤采用环肺静脉消融术式即有良好效果，而对单纯环肺静脉消融不成功者结合节段性肺静脉消融及碎裂电位消融可进一步提高成功率。
Circumferential pulmonary vein ablation alone is enough for paroxysmal AF treatment, while it combined with segmental pulmonary vein ablation and CFAEs ablation may result in high successful rates.
