摘要
目的评估射频消融术对不典型房室结折返性心动过速治疗效果.方法自2007年1月至2012年6月,昆明医科大学附属延安医院收住的673例房室结折返性心动过速(AVNRT)患者接受射频消融术治疗,其中慢快型AVNRT患者636例(典型AVNRT组),快慢型AVNRT患者16例和慢慢型AVNRT患者31例(不典型AVNRT组),所有患者均在窦性心律下或心房起搏下接受慢径消融术.结果不典型AVNRT组和典型AVNRT组在操作时间、急性期成功率方面比较差异无统计学意义,分别为(63±21)min vs(67±29)min和100%vs100%,P>0.05,不典型AVNRT组的复发率高于典型AVNRT组,为6.3%vs 1.4%,P<0.05,2组患者均未出现严重消融相关并发症.结论射频消融术治疗不典型AVNRT安全有效.
Objective To evaluate the efficacy of radiofrequency catheter ablation in the treatment of atypical atrioventricular nodal reentrant taehycardia (AVNRT) Methods From January 2009 to June 2012, 673 consecutive patients with AVNRT were enrolled, among which 636 patients were slow-fast AVNRT (typical AVNRT group) , the other 16 patients were fast-slow AVNRT and 31 patients were slow-slow AVNRT (atypical AVNRT group) . All patients were received catheter ablation slow pathway during sinus rhythm or atrial pacing which ensure 1:1 conduction via the fast pathway. Results There were no significant differences in operation time and acute success rate between atypical AVNRT group and control group (P 〉 0.05), which were (63 ± 21) min vs (67 ± 29) min and 100% vs 100%, respectively. The recurrence rate of atypical AVNRT group was significant greater than that of control group, 6.3% vs 1.4% (P 〈 0.05) Conclusion Radiofrequency catheter ablation of the slow pathway is a feasible and efficient approach to treat atypical AVNRT.
