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 investigate the relationship between time of T wave inversion and left ventricular function in patients with acute myocardial infarction (AMI). Methods: The T wave inversion time was monitored in 40 patients with acute myocardial infarction. Left ventricular function was measured by radionuclide ventriculography 3 to 4 weeks after onset. Results: Left ventricular ejection fraction (LVEF), peak ejection rate and peak filling rate were significantly higher in T-wave inversion within 24 hours than in 72 hours and 24-72 hours. Correlation analysis showed that LVEF, peak ejection rate and peak filling rate were negatively correlated with time of T wave inversion (r = -0.825, -0.793, -0.738, P <0.001, respectively) . Conclusion: Left ventricular function is closely related to T wave inversion time after acute myocardial infarction.
