经导管射频消融术治疗特发性室性心动过速的临床应用研究

The clinical research of radiofrequency catheter ablation of ventricular tachycardia in patients without structural heart disease.

目的:通过经导管射频消融术的方法治疗特发性室性心动过速,评价该治疗方式的有效性及安全性。方法:选择1999年4月—2004年5月期间在鞍钢铁东医院心脏内科诊断为特发性室速的住院患者60例,采用激动标测和起搏标测。结果:56例患者中有52例即时消融成功,消融成功率92.8%,其中ILVT者为90.9%,RVOT者为95.7%。结论:经导管射频消融术治疗特发性室速疗效确切,成功率高,复发率低,应为治疗特发性室速的首选方法。

Objective: Results of radiofrequency catheter ablation of 60 patients with ventricular tachycardia without structural heart disease were analyzed in order to improve the rate of success and decrease complications.Methods:To review the 60 patients with ventricular tachycardia who were admitted into hospital from Apr 1999 to May 2004 by mapping of electrophysiology and pacemaker.Results:52 cases of ventricular tachycardia were ablated successful in the first attempt, rate of success was 92.8%, ILVT was 90.9%, RVOT was 95.7%.Conclusions:Radiofrepuency catheter ablation is a safe and effective method for the therapy of ventricular tachycardia in patients without structural heart disease.
