Measurement of normal healthy persons and AMI patients admitted in 24h first 12 lead ECG Tp-Te interval，12 lead average calculation the Tp-Te interval，on the measurement results of subgroup analysis to compare.Result The observation group 12 lead the average Tp-Te interval were all significantly prolonged (Plt;0.05). The observation group in the incidence of ventricular arrhythmias is more without the occurrence of ventricular arrhythmias in 12 lead the average Tp-Te interval compared with a very significant difference (Plt;0.05).Conclusion ECG Tp-Te interval could reflect AMI transmural dispersion of repolarization changes，AMI ventricular arrhythmias is not the occurrence of ventricular arrhythmias were significantly prolonged Tp-Te interval，Tp-Te interval is expected to become the prediction of AMI occurring in patients with ventricular arrhythmia clinical indicators. 【Key words】 acute myocardial infarction Tpeak-Tend interval Clinical significance Recent clinical prognosis 寻找能够准确预测恶性室性心律失常发生的无创性
