Abstract：Objective The ventricular gradient(VG) represents the metabolic abnormalities of myocardial repolarization itself and the observation of VG contributes to the identification of primary and secondary T wave changes, which provides a new reference index for clinical diagnosis of coronary heart diseases and primary electrocardiorelated diseases.VGH bears a good capacity of predicting ventricular arrhythmias for ICDimplanted patients. There lies a strong connection between VGx and the diagnosis of pulmonary artery hypertension and prediction of death rate.TCRT is significantly positive correlated with forward mortality of patients with myocardial infarction.
