摘要
目的 :分析阵发性室上性心动过速患者行射频消融术后复发的原因 ,探讨降低术后复发的方法。方法 :13 2例阵发性室上性心动过速患者 ,行射频消融术 ,术后每 3～ 6个月随访 1次 ,随访 4～ 2 4个月。结果 :13 2例患者中 ,复发 10例 ,总复发率 7.5 8% ,其中房室结折返性心动过速复发率为 6.5 2 % ,左侧房室旁路介导心动过速复发率 5 .89% ,右侧旁路介导心动过速复发率 14 .2 8%。行射频消融术患者中 ,前 70例复发率 11.43 % ,后 62例复发率 3 .2 2 %。结论 :精确的靶点标测、熟练的操作技巧以及消融方式的正确运用是降低射频消融术复发率的关键。
Objective To analyze of the factors for recurrence of paroxysmal supraventricular tachycardia after radiofrequency catheter ablation (RFCA) in order to reduce the recurrent rate.Methods RFCA was performed in 132 patients with atrioventricular node reciprocal tachycardia (AVNRT) or atrioventricular reciprocal tachycardia and the factors associated with recurrence were analyzed.Results During 4 to 24 months′ follow-up,recurrences were found in 10 cases.The overall recurrent rate among 132 patients was 7.58%.The recurrent rate was 6.52% in patients with AVNRT,5.89% in patients with left atrioventricular by-pass(AP) and 14.28% in patients with right AP.The recurrence rate was 11.43% in the 70 patients receiving radiofrequency ablation earlier,and 3.22% in the 63 patients later.Conclusion Accurate targeting,full mastery of the technique and methods of radiofrequency catheter ablation are key factors to reducing the recurrent rate.
