Background

Coronary heart disease myocardial infarction refers to severe and persistent myocardial necrosis caused by myocardial ischemia due to rapid reduction or interruption of coronary artery blood supply, is a more serious type in coronary heart disease, has the morbidity increasing year by year, and has the trend of more and more younger morbidity people with extremely high mortality.

In the teaching of coronary heart disease and myocardial infarction, the electrocardiogram is mainly used for assisting the teaching, and because the electrocardiogram relates to an electrocardiogram phasor loop and a four-dimensional space imagination, students generally reflect that the pathological change area can not be directly known. For the deficiency, the technical innovation of the existing teaching assistance is needed.

With the development of interventional therapy for coronary heart disease and myocardial infarction, the death rate of the disease is obviously reduced, but because the patient is not aware of the severity of the disease, the clinician and his family members are difficult to understand the intension of the disease and the necessity of emergency operation when communicating with the patient, and the interventional therapy for emergency operation is often rejected.
