摘要 目的了解老年慢性心力衰竭患者心电图QRS波时限延长的临床意义。方法将入选的408例老年心力衰竭患者根据QRS波时限分为≥120ms组(82例)和<120ms组(326例),比较两组患者QRS波时限与左心室射血分数(LVEF)、左心室短轴缩短分数(LVFS)、NYHA心功能分级、左心房大小、左心室大小、二尖瓣返流、左心室壁厚度和住院病死率。结果 (1)QRS波时限<120ms组的LVEF及LVFS均值较≥120ms组大(P<0.01);(2)QRS波时限≥120ms组左心房、左心室均值较<120ms组大(P<0.05);(3)QRS波时限≥120ms组二尖瓣返流率(72.2%)较<120ms组(67.0%)高;(4)两组患者NYHA心功能分级、左心室壁厚度和住院病死率比较,差异均无统计学意义(P>0.05)。结论心电图QRS波时限对判断老年心力衰竭患者病情具有一定参考价值。
