If there are ST-T changes in the ECG, you can take proper rest, avoid exertion and monitor the changes in the ECG. However, if the organic heart disease is caused by a primary cause such as hypertension, viral myocarditis or coronary atherosclerotic heart disease, the cause should be actively searched for, and after determining the cause, medication should be taken regularly and quantitatively, and if necessary, treated by surgery or other means.
