目的:目前正在与不同的程序执行端点导管消融治疗持续性房颤(AF)。当房颤消融期间过程没有结束,电复律在不同的除颤阈值(DFT)根据AF的特点和心房电生理基板进行。我们试图评估心房DFT的导管消融的临床转归持续性房颤后的影响。 方法和结果:我们研究了128持续性房颤患者(年龄63±9岁,男性106)。环肺静脉电隔离结束后,进行了左心房基质消融房颤之前终止或全部确定复杂碎裂电位被淘汰。如果房颤消融过程中没有终止,内部复律协议开始在5J,并逐步增加在5焦耳的步骤,直到成功复律完成。程序自动对焦终止是在50例(A组)来实现的。房颤终止了与复DFT≤10法官在47例(B组)和DFT> 10焦耳31例(C组)。在14±7随访个月后1.3±0.5会话,47(94%),A组患者中,42(89%),B组的患者,和14(45%),C组患者维持窦性心律。在B组和C组,DFT(危险比5.54,P <0.001),房颤持续时间(危险比3.74,P = 0.011),多元分析,反复发作性心​​律失常的独立预测因子。 结论:AF时没有完成预定的逐步消融,进一步广泛消融后终止,终止AF可能是不必要的,如果自动对焦可以成功地在低DFT终止电复律。
