摘　　要：目的:评估在消融指数指导下,环肺静脉电隔离术是否安全有效及不同术者之间环肺静脉电隔离率是否存在可重复性。方法:接受导管消融治疗的房颤患者90例,根据不同术者分为A、B、C 3组,每组入选30例患者。记录术中肺静脉隔离时间、X线透视时间、肺静脉单圈隔离率。结果:C组患者X线透视时间、肺静脉隔离时间均长于A、B组患者(P<0.05),而A、B组患者差异无统计学意义(P>0.05)。3组患者肺静脉单圈隔离率差异均无统计学意义(P>0.05)。3组患者术中及术后均无手术相关并发症出现。结论:消融指数指导下环肺静脉电隔离术是安全有效的,具有可行性。利用消融指导下不同术者之间的环肺静脉电隔离术质量趋于同质性。Objective:To evaluate the safety and effectiveness as well as reproducibility of circumferential pulmonary vein isolation(CPVI)in different operators guided by ablation index.Methods:Ninety patients with atrial fibrillation undergone catheter ablation guided by ablation index were allocated to group A,B and C according to CPVI performed by three different physicians(n=30 for each group).The clinical data,including the time consumed in CPVI,length of X-ray exposure and the isolation rate,were recorded during operation.Results:The time of X-ray fluoroscopy and pulmonary vein isolation was longer in group C than in group A and group B(P<0.05),yet was not significantly different between group A and group B(P>0.05).There was no significant difference in the rate of pulmonary vein isolation(P>0.05),and no operation related complications occurred among the three groups.Conclusion:CPVI under the guidance of ablation index performed by different physicians can be safe,effective,feasible and homogeneous in the outcomes.
