摘要 目的:比较起搏标测与激动标测在室性早搏(PVC)的射频消融术(RFCA)中的应用。方法:对16例顽固性、单源性、PVC患者行(RFCA)术,按照“起搏标测为主,辅以激动顺序标测”的原则,在心内膜精标PVC起源灶,然后放电消融病灶,使PVC消失或显著减少。静脉滴注异丙肾上腺素下反复程序电刺激,不再能诱发或自发与术前PVC相同的PVC或VT,为消融成功。结果:9例患者单行起搏标测到与自发PVC形态相同的心电图,7例消融成功,1例在消融出现成功迹象,静滴异丙肾上腺素验证疗效时,出现尖瑞扭转性室速(TdP),立即经胸电击复律,后改行ICD植入,1例消融失败。7例患者辅以激动顺序标测,5例消融成功。16例患者经5~35月随访,无1例死亡或复发。结论:对PVC行RFCA术中起搏标测获得的定位信息多于激动顺序标测;提高成功率的关键是“以起搏标测为主辅以激动顺序标测”。
