摘　　要：作者测定分析１００例急性心肌梗死（ＡＭＩ）患者住院第３ｄ的１７导联心电图ＱＴ间期离散度（ＱＴｄ）及ＪＴ间期离散度（ＪＴｄ），并以１００例正常人作对照。结果表明：ＡＭＩ组的ＱＴｄ及ＪＴｄ较正常组明显增大，差异非常显著（Ｐ＜０．０１）。ＡＭＩ泵功能级别（Ｋｉｌｉｐ分法）与ＱＴｄ及ＪＴｄ呈正相关，即泵功能级别愈高，则ＱＴｄ，ＪＴｄ值愈大（ｒ分别为０．９９与０．９５）。The QT dispersion(QTd) and JT dispersion(JTd) on the third day of acute myocardial infarction (AMI) in the 17 leads electrocardiogram of 100 patients were measured and analysed, and compared with those of 100 normal individuals The results indicated that the QTd and JTd in AMI group were more greater than those of normal group, the differences were significant(P<001) The severity of cardiac pumping function of AMI patients (according to Killip classification): Grade Ⅰ, grade Ⅱ, geade Ⅲ, grade Ⅳ, was positively correlated with QTd and JTd, namely, the higher the grade of cardiac pumping function, the greater the value of QTd and JTd (r were 099 and 095 respectively)
