摘　　要：目的:评价Visitag软件在心房颤动(房颤)环肺静脉电隔离术中的临床疗效。方法:接受导管消融治疗的房颤患者60例,随机分为Visitag组30例及对照组(关闭Visitag模块)30例。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;Visitag组将环肺静脉消融环分为8个节段,记录每个节段消融导管压力数值,计算各节段总的压力平均值。结果:Visitag组较对照组提高了PVI的单圈隔离率(P<0.05),但两组间的肺静脉隔离时间、X线透视时间差异无统计学意义(P>0.05),左肺静脉前下嵴部在整个消融过程中贴靠压力最低。结论:环肺静脉电隔离术中利用Visitag软件,可以获得更好的连续性、透壁性组织损伤,提高肺静脉隔离成功率。Objective:To evaluate the clinical effect of Visitag module in the circumferential pulmonary vein isolation of atrial fibrillation.Methods:Sixty patients with atrial fibrillation undergoing catheter ablation were randomly divided into Visitag group(n=30)and control group(n=30).The pulmonary vein isolation time,X-ray exposure time and the pulmonary venous isolation rate were recorded during the operation.In the visitag group,the ablation line was divided into 8 segments,in each which the catheter pressure and total pressures were recorded and calculated.Results:Pulmonary venous isolation rate was significantly increased in Visitag group as compared with the control group(P<0.05),yet there was no significant difference in the isolation time of pulmonary vein and X-ray exposure time between groups(P>0.05),and the attachment pressure at left anterior-inferior ridge of pulmonary vein was the lowest in the whole ablation process.Conclusion:Use of Visitag module can improve the continuous and transmural tissue injury and the success rate during the circumferential pulmonary vein isolation.
