摘　　要：目的：探讨急性心肌梗死（ＡＭＩ）患者出现Ｔ波倒置的时间与左心室功能的关系。方法：监测４０例急性心肌梗死患者Ｔ波倒置的时间，并于发病后３～４周行核素心室造影测定左心室功能。结果：２４小时内出现Ｔ波倒置者左心室射血分数（ＬＶＥＦ）、高峰射血率、高峰充盈率均明显高于７２小时以上及２４～７２小时者。相关分析提示ＬＶＥＦ、高峰射血率、高峰充盈率均与Ｔ波倒置出现的时间呈负相关（ｒ分别＝－０．８２５，－０．７９３，－０．７３８；Ｐ均＜０．００１）。结论：急性心肌梗死后左心室功能与Ｔ波倒置时间关系密切。Objective:To study the relationship between the duration of T wave inversion and left ventricular function in patients with acute myocardial infarction (AMI). Methods:The duration of T wave inversion of 40 AMI patients were monitored and radionuclide ventriculography was performed within 3 4 weeks after infarction to test the left ventricular function. Results:Patients with the duration of T wave inversion within 24 h had better left ventricular functional status with left ventricular ejection fraction (LVEF);peak ejection rate and peak filling rate significantly higher than those within 24 72 h and over 72 h.LVEF,peak ejection rate and peak filling rate negatively correlated with the duration of T wave inversion ( r =-0 825,-0 793 and -0 738,respectively,all p <0 001 ). Conclusion:Left ventricular function is closely related to the duration of T wave inversion in patients with AMI.
