摘要 目的:评估固定的长AV间期下的DDD起搏模式对病态窦房结综合征(SSS)患者在减少心室起搏方面的效果;比较应用固定的长AV间期保留自身房室传导与最适AV间期下房室顺序起搏两种模式的优劣性,为此类患者选择具有最佳血流动力学效应的起搏参数设置提供临床依据。方法:连续选取2009年5月至2011年4月在我院因SSS而安置双腔心脏永久起搏器进行治疗的55位患者作为研究对象,分3次随访进行,每次随访时间间隔为2个月,将起搏器程控与超声测量相结合,进行两种不同AV间期下房室顺序起搏模式的血流动力学效应评估与对比。结果:与临床经验性AV间期相比,固定的长AV间期下的房室顺序起搏使心室起搏百分比由在31.8%降低至1.18%(P=0.00017);由最适AV间期下转为固定的长AV间期(350ms)下的房室顺序起搏模式后,心脏总体舒张和收缩功能指标(Tei指数)存在差异,且以左室Tei指数下降更为显著(0.67±0.17比0.45±0.09,P<0.0001)。结论:固定的长AV间期(350ms)下的房室顺序起搏能够有效减少心室起搏,且在血流动力学方面优于最适AV间期下的房室顺序起搏。
