| 摘 要： | 对９８例急性心肌梗死（ＡＭＩ）患者发病２４小时内首次心电图（ＥＣＧ）的ＱＴ间期离散度（ＱＴｄ）进行测定分析，探讨其对ＡＭＩ预后判断的意义，结果表明：室性心动过速（ＶＴ），心室颤动（Ｖｆ）及猝死者的ＱＴｄ显著延长于ＶＴ，Ｖｆ及非猝死者（Ｐ〈０．０１）。前壁心肌梗死组长于下壁心肌梗死组（Ｐ〈０．０１），认为ＱＴｄ可作为早期评价ＡＭＩ预后的重要指标。

| Abstract: | We measured and analysed the QT dispersion (QTd)in the first ECG in 98 patients who suffered from acute myocardial infarction(AMI)within 24 hours to study its evaluation of AMI prognosis. The results showed that the QTd in patients with ventricular tachycardia(VT), ventricular fibrillation (VF) and sudden death were much prolonged than those without them(P<0. 01)and also the QTd with an- terior myocardial infarction was much more prolonged than that with inferior(P<0. 01). We consider that the QTd may be regarded as an important index of early evaluation of AMI prognosis. |
