摘要
目的探讨标测特发性室性心动过速(IVT)有效靶点的方法及对射频消融成功的影响。方法8例IVT的病人,其中右室流出道特发室速(RVOT)5例,左室特发室速(ILVT)3例,先采用激动标测,然后采用起搏标测,标测到靶点后行射频消融。结果8例室速病人均一次消融成功,无复发。结论不论RVOT或ILVT,激动标测+起搏标测具有很高的准确性。
Objectives The role of combining activation with pace mapping to guid e radiofrequency catheter ablation of idiopathic ventricular tachycardia was inv estigated in 8 patients. Methods 8 patients [aged 32-66 (mean age, 39.6±15.8) years, 5M/3F, 5 patients with RVOT, the other were ILVT] with IVT were mapped w ith combining activation with pace mapping and radiofrequency ablation (RFCA). R esults All 8 idiopathic ventricular tachycardias were mapped successfully. Cath eter ablation was performed in all ventricular tachycardias (100%) in 8/8 patien ts. And all were successfully ablated. No recurrence of ventricular tachycardia was observed. No major complication or death occurred. Conclusions Combining a ctivation with pace mapping can be effectively used to map and guide radiofreque ncy catheter ablation of idiopathic ventricular tachycardias.
