摘要 目的研究急性心肌梗死(AMI)合并心律失常与QT离散度(QTd)的关系。方法对来宁乡县中医院住院诊治的90例AMI患者分为3组:A组:恶性心律失常的36例;B组:潜在心律失常41例;C组:无心律失常13例,发病24h内做常规心电图检查,进行心电监护,记录心电图的情况,计算QTd,分析AMI合并心律失常与QT离散度的关系。结果①3组患者QTd、QTcd大小比较差异具有统计学意义(P<0.05),且呈现出递减规律:A组>B组>C组(P<0.05);②QTcd≥60ms的AMI患者心律失常的发生率高达90.3%,明显高于QTcd<60ms的AMI患者,差异具有统计学意义(P<0.05)。结论 QTd值是监测心律失常发生情况的一项重要指标,对AMI合并心律失常的治疗具有一定的指导意义,AMI患者QTd值越大,心律失常发生率越高。
