摘要(Abstract)：
目的 分析导管射频消融大静脉肌袖电隔离治疗阵发性心房颤动 (房颤 )早期复发与延迟成功发生率的关系 ,并探讨其可能的机制。方法 阵发性房颤患者在环状标测电极指导下行靶肌袖和 或全部大静脉肌袖的导管射频消融电隔离治疗 ,对于术后一周内经心电图和动态心电图证实的房颤复发病例 ,继续随访其房颤发作情况。结果 131例患者共接受电隔离治疗 15 9次 ,随访 10 4例(79 3% ) ,失访 2 7例。平均随访 112± 37d时无房颤发作 5 9例 (5 6 7% ) ,房颤发作明显减少和持续时间明显缩短 7例 ,总有效率 6 3 5 %。平均随访 380± 2 2 6d时无房颤发作 81例 (77 8% ) ,房颤发作明显减少和持续时间明显缩短 4例 ,总有效率 80 8%。结论 阵发性房颤肌袖电隔离治疗后早期复发并不意味着房颤治疗的失败 ,部分病例 (17 3% )可以发生延迟成功。
