摘要
目的探讨典型房室结折返性心动过速(AVNRT)合并有房性心动过速(简称房速)患者的临床特点及电生理表现。方法对2009～2011年采用射频消融治疗的典型AVNRT患者290例,分析慢径路消融成功后,仍然能反复诱发出房速的病例特征。结果 10例AVNRT患者(3.4%)合并存在房速,年龄40.2±14.9岁,9例为女性。在成功慢径消融后,仍可诱发出房速,均行射频消融治疗成功。其中右房后壁(界嵴)房速6例,无冠窦房速1例,三尖瓣环房速3例。结论 AVNRT患者可合并房速,常见部位为右房,以右房后壁为多见。
Objective To investigate the clinical features and electrophysiologic characters of typical atrioventricular nodal reentrant tachycardia （AVNRT） with atrial tachycardia（AT） in patients. Methods Two hundred and ninety pa- tients with typical AVRNT who underwent radiofrequency ablation from 2009 to 2011 in Beijing Anzhen Hospital were en- rolled successively. The cases still repeatedly induced AT whose slow pathway ablation was successful were analyzed for their clinic features. Results Ten patients （3.4%） presented AT. The mean age of them was 40.2 ± 14.9. Nine cases were female. After the ablation of slow pathway, AT could be induced. All of them underwent radiofrequency ablation and the procedures were successful. 6 cases bad right atrium posterior wall AT, 1 cases had non-coronary sinus AT and 3 cases had tricuspid annulus AT. Conclusion AVNRT may accompany with AT. The common site is the fight atrium posterior wall.
