摘　　要：目的 :总结 78例射频消融术 (RFCA)治疗室上性心动过速 (SVT)临床资料。方法 :应用RFCA技术治疗难治性SVT。结果 :房室折返性心动过速 (AVRT) 5 2例 ,共 5 4条旁路消融成功 49条 ,成功率为 90 .7%。其中左侧旁路成功率 (97.6 % )明显高于右侧 (6 6 .6 % )。房室结折返性心动过速 (AVNRT) 2 6例 ,仅 1例失败 ,成功率为 96 .1%。 78例总成功率为 92 .5 %。本组无 1例严重并发症。随访 2～ 42个月 ,5例复发 ,经再次消融成功。结论 :RFCA为治疗SVT安全而有效的方法 ,靶点标测。Objective:To analyze results of radiofrequency catheter ablation(RFCA).Methods:RFCA technique was applied in treating supraventricular tachycardia.Results:There were 54 accessory pathways(AP) in 52 patients with SVT mediated by atrioventrcular reentry(AVRT),49 APS had been ablated successfully.Success rate was 90.7%.Among them success rate of left AP(97.6%) was higher than that of right AP( 66.6 %).In 26 patients with SVT mediated by atrioventricular node reentry(AVNRT),only one case was failed to be ablated,success rate was 96.1%.The total success rate of 78 patients was 92.5%.No severe complications were found.During follow up period(2～42 months) SVT recurrenced in 5 patients.All of them were ablated successfully again.Conclusions:RFCA is safe and effective method in treating SVT.It was emphasized that target mapping,control of energy and time of ablation were key to success.
