摘要
目的:评价EnSite NavX三维标测系统引导下应用导管射频消融治疗房室折返性心动过速(atrioventricular reentrant tachycardia,AVRT)的效率及优势。方法:选择2012年3月至2015年6月经食管调搏提示逆行P’波呈偏心性传导的拟诊AVRT患者91例。将入选患者随机分为研究组和常规组,研究组使用EnSite NavX三维标测系统(n=51),常规组使用常规X线曝光(n=40),两组进行心内电生理检查及消融,比较两组的手术操作时间、X线曝光时间、放电次数、放电时间、手术成功率。结果:与常规组相比,研究组手术时间显著缩短[(76.7±21.3)min对(93.2±28.5)min]、X线曝光时间显著缩短[(10.2±6.7)min对(17.3±8.3)min]、放电次数显著减少[(7±3)次对(15±8)次]、放电时间显著缩短[(6.7±2.3)min对(14.2±6.7)min],P<0.01。两组手术即时成功率无统计学差异。结论:EnSite NavX三维标测系统引导射频消融治疗AVRT可明显缩短X线曝光时间与手术时间,减少放电次数和时间。
Objective：To evaluate the efficiency and advantage of radiofrequency catheter ablation（RFCA）of atrioventricular reentrant tachycardia（AVRT）under the guidance of EnSite NavX threedimensional mapping system. Methods：A number of 91 patients with AVRT received RFCA were divided into study group using the EnSite NavX system（n=51）and conventional group using X-ray（n=40）.The operation time,fluoroscopy time,discharge frequency,discharge time,and success rate of operation were compared between two groups. Results：Compared with conventional group,the study group had a significantly shorter operation time [（76.7±21.3）min vs.（93.2±28.5）min],fluoroscopy time[（10.2±6.7）min vs.（17.3±8.3）min],discharge time [（6.7±2.3）min vs.（14.2±6.7）min],and significantly fewer discharge frequency [（7±3）vs.（15±8）],P〈0.01.The immediate success rate of operation had no significant difference between two groups. Conclusion：RFCA of AVRT under the guidance of EnSite NavX three-dimensional mapping system can reduce X-ray fluoroscopy time,operation time,discharge frequency and time.
