摘　　要：目的:探讨QT间期离散度(QTd)对AMI近期预后的预测价值。方法:经EKG检测6 4例AMI患者在发病2 4小时内获得不同导联的QT间期,每导联均测3～5个QT间期。结果:室性心动过速(VT)、心室颤动(Vf)及猝死者的QTd明显长于无VT ,Vf及非猝死者。结论:心电检测QTd的变化是判断AMI近期预后的一项灵敏指标。To study the QTd in 64 patients with acute myocardial infarction to evaluate the value of short term prognosis in acute myocardial infarction. Results:The QTd in ventricular tachycardia, ventricular fibrillation and sudden deaths were obviously longer than that in non-ventricular tachycardia. Non-ventricular fibrillation and non-sudden deaths (P<0. 01); The QTd in patients with anterior wall infarction was obviously longer than that in patients with postern inferior myocardial infarction(P<0. 01).The fact suggests that QTd is a sensitive predictor for short term prognoses of patients with acute myocardial infarction.
