摘　　要：目的 分析急性心肌梗死(AMI)患者QT离散度(QTd)的变化和临床意义。方法 记录 92例AMI患者及60例无心脏病者的心电图,测量QT间期,计算QTd。结果(1)AMI组入院时QTd、QTcd均明显高于对照组(P<O.001)。(2)AMI死亡亚组QTd、QTcd明显高于生存亚组(P<0.001)。③QTd≥80ms的 AMI患者其死亡率及其他冠心病发生率均高于QTd<80ms者。结论 QTd简单、可靠、无创,对AMI的早期诊断及预后有一定的临床价值。Objective Analyses the condition and clinical meaning of QT dispersion is patients with acute myocardial infarction (AMI). Methods echoed the ECG of 92 patiently with AMI and 60 people no heart disease, measure the QT interval and count the QTd. Results (1)The QT dispersion increased obviously in the early of AMI(66±30ms,control group 39± 16ms,P<0. 001). (2)In the patients with AMI,the QT dispersions have a obvious difference in the death group(105±25ms) and in the survivor group(58±18ms,.P<0. 001). (3)The mortality of the patients with AMI whose QTd≥80ms is greater than that QTd<80ms(62. 5% to 3. 3%,P<0. 001). Conclusion QTd,because it is simple reliable and non-invasive,have great value in the early diagnosis and the prognosis judgment of AMI.
