Coronary atherosclerotic heart disease is a type of disease in which the oxygen supply to the heart is reduced due to reduced blood perfusion to the heart, which cannot meet the normal physiological metabolism of the heart. In recent years, with the improvement of living standards and changes in dietary structure, the incidence of coronary heart disease is gradually increasing. In clinical practice, electrocardiogram is mostly used for early heart diseases detection. Abnormal ST segment and T wave of electrocardiogram are important basis for diagnosis of coronary heart disease. Vectorcardiogram is one of the diagnostic contents of electrocardiogram, and its changes are related to the occurrence, development and prognosis of many cardiogenic diseases.
