摘　　要：测定１０７例急性心肌梗塞（ＡＭＩ）患者第三心肌梗塞日的ＱＴ间期离散度（ＱＴｄ）和ＪＴ间期离散度（ＪＴｄ）．并以１００例正常人作对照。结果显示：ＡＭＩ组ＱＴｄ、ＪＴｄ较对照组显著增大（均Ｐ＜０．００１）。住院期间死亡组（３Ｏ例）ＱＴｄ与ＪＴｄ较存活组（７７例）明显增大（均Ｐ＜０．００１）。提示以ＱＴｄ、ＪＴｄ增大来评价ＡＭＩ患者的近期预后有一定意义。The QT dispersion(QTd) and JT dispersion(JTd) of ECG in 107 acute myocardial infarction(AMI) patients on the third day were observed,and compared with those of 100 normal individuals,The results showed that QTd and JTd of AMI patients were significantly greater than those of normal group. The QTd and JTd of AMI patients who died subsequently before discharge were significantly greater than those of AMI patients who survived.These indicate that increased QTd and JTd may predict subsequent mortality.
