摘要(Abstract)：
目的 了解左心室和双心室起搏的急性期血流动力学效应。方法 对 16例心电图呈左束支传导阻滞 (LBBB)的晚期心肌病患者行左室游离壁和双心室起搏 ,记录左室、双心室和基础状态下的左室腔内最大压力上升速率 (dP dtmax)、主动脉根部压力和心电图QRS波宽度。结果 左室和双心室起搏分别使左室dP dtmax提高 2 1%和 18% (P <0 0 1) ,左室和双心室起搏组间无显著差异 ;左室起搏和双心室起搏使主动脉收缩压较基础状态升高 6 %和 5 % (P <0 0 1) ,左室和双心室起搏组间差异不显著 ;左室起搏心电图QRS间期缩短不明显 ,而双心室起搏QRS间期明显缩短。结论 对于心电图呈LBBB型的心肌病终末期心力衰竭患者 ,行双心室起搏和左室游离壁起搏均使患者的急性期血流动力学得到显著改善 ,两者的效果相当
