目的 :为了探讨右房 -右室流出道房室顺序双腔心脏起搏的血液动力学效果和临床潜在应用价值。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)双腔心脏起搏的急性血液动力学特点。方法 :1 6例患者因缺血性心脏病或扩
OBJECTIVE: To investigate the hemodynamic effects and clinical potential of dual-chamber atrial pacing in right atrium-right ventricular outflow tract. We compared the acute hemodynamic characteristics of RA -RVOT atrio-ventricular double lumen pacing and conventional right atrium-right ventricular apex (RA -RVA) double-lumen cardiac pacing. Methods: Sixteen patients had ischemic heart disease or enlargement
