摘要 目的探讨心肌梗死(MI)合并2型糖尿病者(MI+T2DM)和单纯MI者窦性心率震荡(HRT)现象的变化及其临床意义。方法选择32例MI+T2DM(A组)、32例单纯MI(B组)、和33例对照组(C组)作为研究对象。三组人员均行24h动态心电图(DCG)监测,分析单次室性期前收缩(PVS)后HRT的初始值(TO)、斜率(TS)以及TO和TS异常的发生率。结果A、B组TO、TS值明显异常,与C组比较均有显著性差异(P<0.01),A组与B组的TO、TS值比较差异亦有显著性(分别为P<0.05、P<0.01),三组TO及TS异常发生率分别为A组(65.62%、71.85%)、B组(53.12%、59.37%)、C组(12.12%、12.12%)。A、B组异常率明显升高,与C组比较均有显著性差异(P<0.05)。结论MI合并T2DM者HRT现象明显减弱,且HRT异常率增高最明显。HRT可作为MI合并TDM者临床上判断预后的重要心电指标。
