摘　　要：心室复极梯度(ventricular gradient,VG)代表了心肌复极本身代谢的异常,通过对VG的观测有助于原发性与继发性T波改变的鉴别,为临床医师诊断冠心病及原发性心电疾病提供了新的参考指标。VGH对于ICD植入患者发生室性心律失常具有较好的预测性。VGx与肺动脉高压的诊断和死亡率的预测有很大的相关性。TCRT与心梗患者远期死亡率呈明显正相关。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 electrocardio-related diseases.VGH bears a good capacity of predicting ventricular arrhythmias for ICD-implanted 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.
