What does it mean possible left atrial enlargement?

Health conditions most commonly associated with the enlargement of the left atrium include high blood pressure, atrial fibrillation, mitral valve dysfunction, and left ventricle problems. These conditions can produce elevated left atrial pressures, elevated left atrial volume, or both—leading to LAE.

Chest pain. Discomfort in other areas of the upper body, including one or both arms, the back, neck, jaw, or stomach. Severe shortness of breath. Fainting.

Can ECG detect heart enlargement?

An ECG (electrocardiogram) records the electrical activity of your heart at rest. It provides information about your heart rate and rhythm, and shows if there is enlargement of the heart due to high blood pressure (hypertension) or evidence of a previous heart attack (myocardial infarction).

What does probable left atrial enlargement mean?

When someone has left atrial enlargement, it can also be a sign of congestive heart failure . Heart failure occurs when a person’s heart cannot pump enough blood to meet the needs of the body. It can lead to fatigue, weight gain, and a buildup of fluid in the lungs, liver, and the legs.

What are the causes of mild left atrial enlargement?

causes the heart to work harder as it pumps blood to the body.

What is treatment for enlarged left atrium?
