希氏束旁旁道是临床少见的间隔旁道 (AP) ,由于解剖部位特殊 ,邻近希氏束 ,消融时易造成房室传导阻滞。本文总结笔者 2 0 0 1年在北京大学人民医院电生理室研修期间的 2 1例希氏束旁旁道患者经射频消融 (RFCA)治疗成功资料 ,对此特殊AP的心电图特点及RFCA治疗进行讨论。1　资料 His bundle next to the bypass is a clinically rare interval bypass (AP), due to special anatomy, adjacent to His bundle, ablation is likely to cause atrioventricular block. This article summarizes the author in 201 cases of Peking University People’s Hospital electrophysiology room during the training of 21 cases of Hisaxillary bypass by radiofrequency ablation (RFCA) successful treatment of data on the characteristics of this particular ECG and ECG RFCA treatment discuss. 1 data
