报告射频消融治疗房室旁道折返性室上性心动过速37例的体会。其中左侧旁道31例,右侧旁道6例,使用端电极为4mm的可操纵电极导管,分别在左室二尖瓣环下房室环处和三尖瓣环心房侧标测最短的A-V间期和最短的V-A间期为定位指标。射频电流释放于端电极与体表板状电极之间。6例左侧旁道中成功28例,6例右侧旁道均未阻断。成功的28例平均消融次数10±6次;平均手术时间3.32±1.19h;平均射频输出能量4835±2176J,随访1～13个月无复发。
Report of 37 cases of reentrant supraventricular tachycardia treated by RFA in atrioventricular. The left side of the bypass in 31 cases, the right side of the bypass in 6 cases, the use of the terminal electrode 4mm steerable lead, respectively, at the atrioventricular annulus and mitral annulus at the shortest The AV interval and the shortest VA interval are positioning indexes. RF current is discharged between the terminal electrode and the surface plate electrode. Of the 6 cases, 28 cases were successful in the left bypass and 6 cases were not blocked in the right side. The average number of successful ablation in 28 cases was 10 ± 6 times. The average operation time was 3.32 ± 1.19 hours. The average RF output energy was 4835 ± 2176J. No recurrence was observed in 1 ~ 13 months follow-up.
