摘要
目的:探讨间隔部房室旁道射频消融术发生房室传导阻滞的原因。方法:回顾分析67例间隔部旁路参与的房室折返性心动过速患者射频消融的临床资料。结果:消融成功率为98.5%(66/67),3例发生Ⅱ度至Ⅲ度房室传导阻滞,发生率为4.55%(3/66)。结论:虽然房室旁路的消融手术成功率高、操作安全,但间隔部旁路消融仍具有挑战性。熟练的心电生理和解剖知识、精确标测、低功率放电、增加消融电极稳定性,有助于减少房室传导阻滞的发生。
Objective：To investigate the cause of atrioventricular block（AVB） triggered by radiofrequency ablation（RFCA） in the treatment of septal accessory pathway.Methods：We retrospectively analyzed the clinic features of patients who were cured by RFCA with septal accessory pathway.Results：The success rate for ablation of septal accessory pathway was 98.5%（66/67）.AVB occurred in 3 of 66 patients（4.55%） of second-degree block to third-degree block.Conclusion：Although ablation of accessory bypass tracts is a successful and safe procedure,septal pathways bypass remains challenging.Accurate knowledge of cardiac electrophysiology and anatomy involved,precise mapping,lower ablation energy,enhanced catheter stability may reduce AVB.
