Abstract： Right ventricular dysfunction or right heart failure is a complex clinical syndrome and often leads to a poor prognosis and high mortality. In order to detect right ventricular dysfunction at an early stage, provide a therapy guidance and evaluate treatment outcomes， right ventricular function evaluation has aroused more and more concern in clinical physicians. With the advantages of being non-invasive， accuracy and repetitiveness， echocardiography is used extensively in the assessment of heart function. In this review， we focus on how to use echocardiography to evaluate right ventricular function easily, efficiently， accurately and sensitively， and provide a good foundation for its further clinical application.
