作者采用射频消蚀房室结慢径治疗３０例房室结折返性心动过速患者，２８例首次消蚀成功，２例再次消蚀成功。其中单纯消蚀慢径２５例，慢径和逆传快径同时消蚀４例，１例发生暂时性完全性房室传导阻滞。平均随访１０．９±８．８个月，未见复发。本文对慢径消蚀定位方法、预测消蚀成功的标志及房室传导阻滞的预防进行了探讨。
The authors used radiofrequency ablation of atrioventricular node slow pathway in the treatment of 30 patients with atrioventricular nodal reentrant tachycardia, 28 cases of successful initial eradication, two cases of successful eradication. Among them, 25 cases showed only slow path of eradication, 4 cases of slow path and rapid reverse path erosion, and 1 case had a complete and complete atrioventricular block. The average follow-up of 10.9 ± 8.8 months, no recurrence. In this paper, the slow path erosion positioning method, the prediction of successful erosion signs and prevention of atrioventricular block were discussed.
