目的评价射频消融法治疗房室和房室结折返性心动过速的临床效果和安全性。方法22例患者行心内电生理检查,采用标准程序刺激右心室或右心房,诱发室上性心动过速,并对其进行标测和消融。结果房室旁路13例,其中左心旁路10例,右心旁路3例。房室结双径路9例。22例射频消融成功21例(95.46%),失败1例(4.55%)。1例(4.55%)术后发生暂时性完全性右束支传导阻滞。随访3~14个月,无室上性心动过速复发。结论射频消融治疗房室和房室结折返性心动过速效果肯定,手术安全。
Objective To evaluate the clinical effects and safety of radiofrequency ablation in the treatment of atrioventricular and atrioventricular nodal reentrant tachycardia. Methods Twenty-two patients underwent electrophysiological examination of the heart. Standard procedures were used to stimulate the right ventricle or the right atrium to induce supraventricular tachycardia, which was then labeled and ablated. Results Atrioventricular bypass in 13 cases, including 10 cases of left ventricular bypass, right heart bypass in 3 cases. Atrioventricular node dual pathway in 9 cases. Among the 22 cases, 21 cases (95.46%) succeeded in radiofrequency ablation and 1 case failed (4.55%). One patient (4.55%) had a complete right bundle branch block after operation. Follow-up 3 to 14 months, no recurrence of supraventricular tachycardia. Conclusion Radiofrequency ablation of atrioventricular and atrioventricular nodal reentrant tachycardia positive results, surgical safety.
