Abstract：In recent years, many new advances have arisen in the diagnosis and research of ECG of right ventricular(RV) hypertrophy. In order to determine RV dilatation in patients with heart failure and left bundle branch block, Van Bommel et al proposed three ECG diagnostic criteria, which included the presence of terminal waves in forward direction(late R-wave), low voltages(＜0.6 mV) of QRS complex in all limb leads and the ratio of R/S＜1 in lead V5. Furthermore, the four ECG diagnostic criteria including RV1＞0.6 mV, R/S＞1 in V1 lead, RaVR >0.4 mV and PⅡ>0.25 mV proved to be useful in determining RV hypertrophy in patients with pulmonary arterial hypertension. Recent MESARV study suggested that in diagnosing mild RV hypertrophy, traditional ECG screening criterion had high specificity and yet low sensitivity relatively.
