摘要 目的:探讨三腔起搏器使用QuickOpt优化后对心功能的影响。方法:选取本院自2007年5月至2011年8月成功植入StJude公司的CRT-P或CRT-D(5596或V-350)的慢性心衰患者62例。根据有无使用QuickOpt功能分为优化组32例与未优化组30例。两组患者于术前及术后1、3、6个月均采用心脏超声及心电图检查。记录左室收缩末内径(LVESD),左室舒张末内径(LVEDD),二尖瓣反流面积(MRV)、射血分数(EF)及QRS时限。结果:两组患者心功能各指标于术后1个月即开始好转,QRS时限缩短。与未优化组比较,优化组患者心功能明显好转,在术后6个月尤为明显,两者差异有统计学意义(P<0.05)。结论:CRT术后利用QuickOpt功能进行的快速自动间期优化能显著改善心功能。
