摘要 目的:比较心肌钙蛋白(cTnI)阳性和cTnI阴性患儿的24h平均QT间期离散度(QTcd)的变化,探索用QTcd辅助诊断儿童早期心肌损伤的可能性。方法:以54例cTnI阳性患儿为研究对象,依据24h动态心电图(Holter)的结果分为心律失常组和非心律失常组,利用Holter自带的心电分析系统自动计算每小时的QTcmax、QTcmin值,人机对话算出每小时QTcd/h(QTcd/h=QTcmax-QTcmin)及24h平均QTcd值。结果:cTnI阳性组QTcd明显增大,较病例对照组,正常对照组差异有显著性,cTnI阴性的病例对照组QTcd亦增大,但与正常对照组相比无差异性。结论:24h平均QTcd值增大可作为诊断儿童早期心肌损伤的心电指标之一,为早期治疗提供依据。
