What Is a “possible Anteroseptal Infarct” on an ECG?

A possible anteroseptal infarct on an ECG can mean that a person had a heart attack in the past, or it could also mean that the result is inaccurate, according to HealthTap doctors. If a person has no history of heart disease, it is most likely that the reading is wrong.

A heart attack occurs when a blood clot obstructs a coronary artery completely, explains MedicineNet. The artery supplies blood to the heart and, if obstructed, causes the heart muscle to die. Blood flow needs to be returned to the heart within 20 to 40 minutes; otherwise, irreversible damage of the heart muscle occurs. Atherosclerosis is the main cause of a heart attack and occurs when plaques of cholesterol are deposited in the walls of arteries. The condition can be accelerated by smoking cigarettes, having high blood pressure, having elevated cholesterol and having diabetes mellitus.

The most common symptom of a heart attack is chest pain, notes MedicineNet. Other symptoms may include shortness of breath, nausea and vomiting, although some people experience no symptoms at all. Those that have a silent heart attack with no symptoms may only find out about it with an ECG. To improve the prognosis for a heart attack, doctors reopen blocked coronary arteries through medication and surgery. Future heart attacks can be prevented by aspirin, weight reduction, exercise and by following a low cholesterol diet.
