Abstract：As a simple and feasible inspection method,electrocardiogram(ECG) has vital significance for the diagnosis and treatment of coronary heart disease(CHD). This paper breifly illustrates the roles ECG plays in the identification of CHD diseased region, infarct-related vascellum, staging and prognosis and also in the instruction treatment scheme of CHD.CHD seriously affects the quality of life of patients, however eary identification and proper treatment will bring benefits for them. With the help of ECG, CHD can be identified at an early stage and given proper treatment clinically.
