摘要
采用改良下位法选择性阻断慢径路治疗20例房室结折返性心动过速患者.改良下位法的特点是:不放冠状窦电极,在后前位透视下,以His束电极为定位标志,射频电极从His束电极下方开始消融慢径路.结果20例患者,19例慢径路阻断,术后房室结双径路跳跃现象及房室结折返性心动过速消失,成功率95%(19/20),平均手术时间3.1±1.04小时,x线曝光时间29±11.2分,随访1～13月,1例复发,本文对改良下位法的方法学和机理进行了探讨.
Selective ablation of the slow pathway by modified inferior approach in 20 patients with atrioventricular node reentrant tachycardia was reported. Character of the modified inferior approach include: only using His bundle catheter to direct RF catheter positioning under posteran-terior view, without inserting coronary sinus catheter, the RF catheter was positioned below His bundle catheter. The result showed: Selective ablation of the slow pathway was successful in 19 patients, the success rate is 95% (19/20). The mean time of operation was 3. 1 ± 1. 04 hours;the fluoroscopic exposure time was 29. 3±11. 3 minutes. One patients had recurred during a period of 11 ~ 13 months follow up. The methodology and mechanism of the modified inferior approach was disscused.
