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.
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。
The number of positive cell and mean of optical density were detected and the trend change was analyzed. The variance analysis and t-test were also performed.
测定阳性细胞数和平均光密度值，分析其变化趋势，并进行方差分析和t检验。
