目的：对21例间隔房室旁路射频导管消融术(RFCA)结果进行分析。总结经验，以期提高间隔房室旁路RFCA的成功率，减少并发症。

方法：对21例间隔房室旁路的电生理特性和射频导管消融方法进行分析和探讨。

结果：21条间隔房室旁路一次消融成功20条，成功率95%。1例左后间隔房室旁路术中出现一过性完全性房室传导阻滞，数分钟后恢复正常。1例右中间隔房室旁路术后1个月出现Ⅰ度房室传导阻滞，余无并发症发生。全部病例随访3～20个月，停用一切抗心律失常药物，均无心动过速发作。

结论：RFCA是阻断间隔房室旁路安全有效的方法。

objective: Results of radiofrequency ablation of 21 patients with septal accessory pathway were analyzed in order to improve the success rate and decrease complications.

Methods: the electrophysiologic features and the radiofrequency ablation methodology of21 cases of septal accessory pathways were analyzed.

Results: twenty accessory pathways were ablated successfully in the first attempt, success rate was 95%; all accessory pathways were interrupted within 10 seconds. short term complete atrioventricular block occurred in one patient, Ⅰ° atrioventricular block after ablation occurred in another patient, no other complication occurred. Within a follow-up of 4 to 20 months, all patients including the unsuccessful one were free from tachycardia recurrence without any antiarrhythmic medication.

Conclusion: radiofrequency catheter ablation is a safe and effective method for the therapy of septal accessory pathway.
