摘　　要：目的观察右室室性心动过速(简称室速)射频消融的近、远期疗效。方法 34例右室室速患者经受了射频消融,其中诊断为特发性右室室速29例,致心律失常性右室发育不全(ARVD)5例。结果 28例特发性右室室速消融成功,1例失败;5例 ARVD 患者诱发出9种室速,5种室速消融成功,另4种室速失败。随访显示,28例特发性右室室速中2例分别于射频消融术后的12和15个月发生新的室性心律失常,进一步检查证实1例为 ARVD,另1例为扩张型心肌病。ARVD 患者组中2例室速复发。结论右室室速射频消融的结果取决于有无器质性心脏病,对于特发性右室室速消融术后再发或出现新的室性心律失常患者,需注意排除 ARVD 或心肌病等器质性心脏病的存在。Objective To evaluate the acute and long-term efficacy of radiofrequency catheter abla- tion in patients with right ventricular tachycardia(RVT).Methods 34 patients with RVT underwent ra- diofrequency catheter ablation,in whom 29 patients was diagnosed as idiopathic RVT(IRVT)and 5 ar- rhythmogenic right ventricular dysplasia(ARVD).Results Radiofrequency catheter ablation was success- fully performed in 28 of 29 patients with IRVT.9 kinds of VT were induced in 5 patients with ARVD,in which 5 kinds of VT was ablated successfully while other 4 not.Follow-up results showed that in 28 pa- tients with IRVT 2 patients had new VT after 12 and 15 months after radiofrequency ablation respective- ly.The results of other examination confirmed that one patient had ARVD and the other had dilated car- diomyopathy.VT recurred in 2 patients with ARVD.Conclusion The results of radiofrequency catheter ablation in patients with RVT depend on whether the patients had organic cardiac disease.If RVT recurs or there is new VT in patients with IRVT after catheter ablation,organic cardiac disease including ARVD or cardiomyopathy should be considered.
