目的 :我们对比研究了右房 -右室流出道 (ＲＡ -ＲＶＯＴ)房室顺序双腔心脏起搏和传统的右房 -右室尖 (ＲＡ -ＲＶＡ)心脏起搏的心室激动顺序、心室收缩同步性变化和心功能的关系。探讨右房 -右室流出道房室顺序双腔心脏起搏治疗心力衰竭的机制。方法 :1 5例缺血性心脏病或扩张
PURPOSE: We compared the ventricular activation sequence of RA -RVOT atrio-ventricular double lumen pacing and conventional right atrial-right ventricular apex (RA -RVA) cardiac pacing, ventricular contraction Relationship between synchronicity and cardiac function. To investigate the mechanism of atrioventricular sequential dual-chamber cardiac pacing in right atrium-right ventricular outflow tract in the treatment of heart failure. Methods: Fifteen cases of ischemic heart disease or dilatation
