摘要
目的：探讨急性心肌梗塞（ＡＭＩ）静脉溶栓治疗 对心电图（ＥＣＧ）校正的ＱＴ间期离散度（ＱＴｃｄ）的影响；方法；用体表心电图１２导联测６５例ＡＭＩ患 者溶栓前，溶栓后３ｈ的ＱＴｃｄ，并对出现与未出现心律失常者的ＱＴｃｄ进行比较。选取３０例正常 人做对照组，取其ＱＴｃｄ作为参考值；结果：ＡＭＩ组溶栓前与对照组ＱＴｃｄ差异显著（Ｐ ＜０．０１），溶栓后再通组ＱＴｃｄ时限缩短，而未通组无明显变化，两者的ＱＴｃｄ比较差异 显著（Ｐ＜０．０１），出现恶性心律失常的ＡＭＩ患者，其ＱＴｃｄ长于无恶性心律失 常出现者（Ｐ＜０．０１）；结论：成功的溶栓治疗可使ＱＴｃｄ缩短，亦可减少恶性 心律失常的发生。
Objective:To investigate the effect of intravenous thrombolytic treatment on QT corrected dispersion(QTcd)in acute myocardial infarction(AMI).Methods:QTcd were measured in 65 AMI patients using 1 2 Lead electrocardiograph pre and 3 hours post intravenous thrombolytic treatmen t.QTcd were compared in patients with and without fatal arrhythmia.Thirty health y persons were in control group.Result:There was a significalnt difference in QT c d between AMI and control group before treatment (P＜0.01).QTcd signif icantly shortened in reperfusion group after thrombolytic treatment,and there wa s ro significant change of QTcd in non-perfusion group.There was a significant d ifference of QTcd between this two groups(P＜0.01).QTcd were longer in patients with fatal arrhythmia than that in patients without fatal arrhythmia.C onclusion:Shortened QTcd and low incidence of fatal arrythmia can be obtained by sucassful thrombolytic treatment in AMI.
