| 中文摘要 | 目的根据经射频消融治疗的左室特发性室性心动过速患者,术中诱发室性心动过速程序的变化以及随访结果,评价室性心动过速消融成功标准的客观性,寻找更可靠的判断标准。方法1994～2008年消融成功并得到随访的146例特发性室性心动过速患者的临床发病情况;第1组68例,常规方法;第2组51例,常规方法结合靶点刺激;第3组27例,导管消融使其体表心电图成为左后分支阻滞图形,在此基础上重复第2组方法。观察3种方法对复发率的影响。结果①38.7%的患者在术中诱发窗口不稳定,存在着随手术时间延长室性心动过速不易诱发的特点。②第1组68例患者复发率为8.8%,第2组51例复发率为3.9%,第3组27例复发率为0%,第3组复发率明显低于第1组。结论形成左后分支阻滞的消融策略结合靶点刺激,有助于提高效果判断的可靠性。; Objective To find a reliable method to reduce the recurrence of catheter ablation procedure for patients with idiopathic left ventricular tachycardia(ILVT). Methods 146 patients with ILVT from 1994-2008 underwent successful catheter ablation and had a response to follow-up.The patients were divided into three groups which include group 1 with traditional method(n=68),group 2 with traditional method plus target site induction(n=51),group 3 with ECG axis changes post ablation plus target site induction(n=27),the data about the variability of induction of idiopathic ventricular tachycardia and reliability of judgment were analyzed. Results 38.7% patients had a variable inductive window during the ablation procedure.Recurrence rates were 8.8%,3.9% and 0% in groups of induction stimulation in traditional site,traditional site plus target site,with ECG axis changes plus target site induction,respectively. Conclusion Ablation procedure to make ECG axis changes and induce stimulation at target site can increase the reliability of successful judgment. |
