Left Atrial Enlargement

Left Atrial Enlargement Left atrial enlargement (LAE) is due to pressure or volume overload of the left atrium. LAE is often a precursor to atrial fibrillation. Also known as: Left Atrial Enlargement (LAE), Left atrial hypertrophy (LAH), left atrial abnormality. P wave changes with Left Atrial Enlargement ECG Criteria for Left Atrial Enlargement LAE produces a broad, bifid P wave in lead II (P mitrale) and enlarges the terminal negative portion of the P wave in V1. ...
