摘要 目的研究扩张型心肌病患者病变程度与心电图QRS波变化的相关性。方法选取我院2014年4月-2016年1月纳入的95例扩张型心肌病患者作为研究对象,收集所有患者完整临床资料进行回顾性分析,并进行心电图分析,观察患者病变程度与心电图QRS波变化的关系。结果心电图结果显示,完全性左束支传导阻滞16例,完全性右束支传导阻滞13例,非特异性心室内传导阻滞20例,从正常QRS波扩宽超过0.11 s的10例;平均QRS波的宽度为(0.13±0.04)s,平均扩宽程度(0.022±0.006)s;QRS波扩宽程度与左心室射血分数呈负相关性(P<0.05)。结论心电图QRS波与扩张型心肌病患者病变程度具有一定相关性,能够直接体现出患者病情进展程度,为尽早治疗提供保障,从而延缓病情发展,延长患者生命。
