摘　　要：目的评价射频导管消融术(RFCA)治疗儿童特发性室性心动过速(IVT)的临床疗效。方法对经RFCA治疗的IVT患儿35例进行分析。随机分为对照组与研究组。对照组采用激动顺序标测法和起搏标测法,研究组在对照组基础上结合多普勒组织成像技术(DTI)进行标测。观察两组放电次数、X线曝光时间及射频能量的差异。结果研究组与对照组比较,放电次数少、X线曝光时间缩短。两组射频消融能量、成功率、复发率无差异。结论RFCA是治疗儿童特发性室速安全、有效的方法。结合DTI进行标测可减少放电次数、X线曝光照时间。Objective To investigate the value of radiofrequency catheter ablation （RFCA） on idiopathic ventricular tachycardia （IVT） in children. Methods The treatment efficiency of 35 patients accepting RFCA from March 2000 to February 2006 was analyzed, which was divided into control group and study group, randomly. The target site of IVT was localized by routine mapping in control group, and study group was localized by routine mapping combining doppler tissue imaging（DTI） on the basic treatment. Results Numbers of diseharge, X - ray exposure time in study group were shorter than that in control group. There were no significance of radiofrequency energy, achievement rates and relapse rates between two groups. Conclusions RFCA is a safe and effective method on IVT. Children are localized combined with DTI shall decrease numbers of discharge and X- ray exposure time.
