I see you have your father's ECG results. An electrocardiogram (ECG) is a very simple and easy-to-run test that shows the heart's electrical activity, and it is called an ECG. Besides, if the ECG shows such disorders as too fast or too slow heartbeats, it can be the reason for heart problems. A heart attack or myocardial infarction may occur because of the symptoms of chest pain, shortness of breath, or dizziness. It can be a result of hypertension that is related to either the heart itself or to stress. Other possible remedies are lifestyle changes including healthy dieting, regular exercising, and stress reduction. It is always necessary to contact the doctor to get your condition assessed and the treatment prescribed.
