经导管射频消融术治疗阵发性室上性心动过速269例分析

Analysis of 269 Paroxysmal Supraventricular Tachycardia Cases Treated with Radiofrequency Catheter Ablation

目的:探讨射频消融术(RFCA)治疗阵发性室上性心动过速(PSVT)的有效性和安全性。方法:回顾分析RFCA治疗阵发性室上性心动过速269例结果,根据体表心电图和心内电生理检查进行RFCA。结果:房室折返性心动过速(AVRT)176例,总成功率97.7%,复发率3.4%,房室结折返性心动过速(AVNRT)93例,总成功率98.9%,复发率4.4%。术中出现短暂性脑缺血发作1例,术后出现Ⅲ度房室传导阻滞1例,无1例因为并发症死亡。结论:RFCA是治疗PSVT的有效方法。并发症和术者的熟练程度、消融靶点的位置、患者全身情况和解剖变异等有关。

Objective：To investigate the validity add security of radiofrequency catheter ablation（RFCA） in the treatment of paroxysmal superventricular tachycardia（PSVT）.Methads：Review the results of 269 cases of PSVT patients lreated with ILFCA which is based on electrocardiogram and cardiac electrophysiologic study.Results：There were 176 eases of atrioverarieular reentrant tachycardia（AVRT） with the success rate of 97.7% and the relapse rate of 3.4%,93 cases of atrioventricular nodal reentrant tachyeardia（AVNRT） with the success rate of 98.9% and the relapse rate of 4.4%.Though we have 1 case of transient isehemic attack in the operation and 1 case of m atrial ventricular block after the operation,we have no death case for the complication of the operation. Coneluslon：RFCA is an effective method in the PSVT treatment.The complication depends on the operator＇ s skill level,the position of ablation target,the general appearance of the patients and the anatomical variation.
