摘要 目的探讨心电图QRS波群时限延长在心力衰竭患者中的临床意义,指导判断预后及治疗。方法入选110例心力衰竭患者,根据QRS波群时限分为≥120m s组和<120m s组,分析两组QRS波时限与NYHA心功能分级,左心室舒张末期内径(LVEDd),左室射血分数(EF),左室短轴缩短分数(LVFS),恶性心律失常发生率、死亡率的关系。结果 QRS波群时限≥120m s组患者左心室舒张末期内径,左室射血分数,左室短轴缩短分数,恶性心律失常发生率、1年内死亡率与正常QRS波宽度组心力衰竭患者对照明显恶化,统计学差异有显著性(P<0.05)。结论 QRS波群时限延长(≥120m s)可作为心力衰竭患者病情严重程度及预后不良的评估方法。
