典型心房扑动合并局灶房性心动过速患者的临床及电生理特点

Clinical characteristics in patients with typical atrial flutter combined focal atrial tachycardia

目的总结典型心房扑动（房扑）合并局灶性房性心动过速（房速）患者的临床特点及电生理特性。方法收集2009年3月至2014年9月在阜外医院心律失常中心成功消融的典型房扑合并局灶房速患者的临床资料及电生理检查结果。结果263例典型房扑的患者中，5例（1．9％）记录到6种局灶房速，其中2例房速起源于界嵴上部、2例起源于右上肺静脉口部、1例分别有起源于左心房后壁及冠状静脉窦口的2种房速。结论极少数典型房扑患者可合并局灶房速，这些局灶房速可来源于多个异位兴奋灶。

Objective To observe the clinical characters and electrophysiological features in patients with typical atrial flutter （AFL） combined focal atrial tachycardia （FAT）. Methods From March 2009 to September 2014 ,the patients with typical AFL undergoing electrophysiological studies in center of arrhythmia, Fuwai Cardiovascular Hospital were enrolled in the study, the clinical characteristics and electrophysiological features were collected. Result Two hundred and sixty three patients were enrolled. Among them,6 different FAT were recorded in 5 patients （ 1.9% ） including FAT originated from the upper Crista in two cases ; FAT originated from the right upper pulmonary vein in two cases;FAT with two kinds of atrial tachycardia originated from the posterior wall of the left atrium and the coronary sinus ostium separately in one case. Conclusion Only a few patients have typical AFL combined with LAT, and these LAT originated from different locations.
