射频消融术治疗阵发性室上性心动过速210例分析

目的评价射频消融术治疗阵发性室上性心动过速的有效性及安全性。方法对210例阵发性室上速患者采用射频消融术治疗,旁路在心室最早激动点（EVA）或心房最早激动点（EAA）消融,双径路则采用慢径改良。结果射频消融术治疗室上性心动过速的总成功率为97.1%（204/210）,其中旁道参与的心动过速119例,成功率95.0%;房室结折返性心动过速91例,消融成功率为100%。4例（1.9%）患者出现并发症。随访期间,3例（1.4%）患者复发,再次接受射频消融术获成功。结论射频消融术是治疗阵发性室上性心动过速安全及有效的治疗手段,成功率高,并发症少,复发率低。

Radiofrequency current ablation for supraventricular tachycardia: A clinical report of 210 patients

Objective To evaluate the efficacy and safety of radiofrequency current ablation for Paroxysmal supraventricular tachycardia（PSVT）.Methods Radiofrequency current ablation（RFCA） was performed in 210 patients with paroxysmal supraventricular tachycardia.The accessory pathway（AP）ablation was performed in the earliest ventricular action（EVA）or the earliest atrial action（EAA）.For the double pathway（DP）,the slow pathway（SP）ablation was performed.Results All patients were treated by radiofrequency current ablation with a total success rate of 97.1%.Among 119 patients with paroxysmal supraventricular tachycardia caused by atrioventricular accessory pathways,atrioventricular accessory pathways were successfully ablated with a success rate of 95.0%.In 91 patients with atrioventricular nodal reentrant tachycardia,the slow pathways were successfully abolished with a success rate of 100%.Complications occurred in 4 patients（1.9%）.During follow-up,PSVT recurred in 3 patients（1.4%）and was permanently eliminated by reapplication of RFCA.Conclusion RFCA is a highly valuable non-drug therapy for PSVT with a high success rate,few complications,and low recurrence.
