摘　　要：目的评估心房下起搏消融房室结慢径的可行性与有效性.方法自2009年8月至2010年4月,有73例房室结折返性心动过速(AVNRT)患者入院接受射频消融术,其中62例慢快型AVNRT和1例慢慢型AVNRT患者(对照组)在窦性心律下进行慢径消融,6例快慢型AVNRT及另4例慢慢型AVNRT患者在持续心房起搏(心房起搏组)并保证快径1:1前传的情况下进行慢径消融.结果对照组和心房起搏组在放电次数、操作时间、急性期成功率方面比较差异无统计学意义,分别为(3.3±1.1)次vs(3.2±1.0)次、(63±21)minvs(59±19)min和100%vs100%,P>0.05,两种消融方法均未出现严重并发症.结论心房下起搏消融房室结慢径有效且可行,可作为治疗AVNRT的一种方法。Objective To evaluate the feasibility and efficacy of radiofrequency catheter ablation of slow pathway under atrial pacing.Methods From August 2009 to Aapril 2010,73 patients with atrioventricular nodal reentrant tachycardia（AVNRT） were enrolled in this study.Among them,62 patients with slow-fast AVNRT and 1 patients with slow-slow AVNRT（control group） received cathter ablation of slow pathway under sinus rhythem,6 patients with fast-slow AVNRT and other 4 patients with slow-slow AVNRT（atrial pacing group） received cathter ablation of slow pathway under atrial pacing which ensure 1：1 conduction via the fast pathway.Results There were no significant difference between conroll group and atrial pacing group in the mean RF pulses applied per patient,operation time and acute success rate,which were（3.3 ± 1.1） vs（3.2 ± 1.0）,（63±21） min vs（59±19） min and 100% vs 100% respectively（P〉0.05）.No severe complications occurred in patients in both groups.Conclusion Atrial pacing during catheter ablation of the slow pathway is feasible and efficient,which can be an alternative approach to treat AVNRT.
