The electrocardiogram (ECG) in mitral stenosis might have no significant abnormalities. Findings suggestive of left atrial enlargement and hypertrophy might be present, such as a broad, bifid P wave in lead II (referred to as P mitrale) and an enlarged terminal negative portion of the P wave in V1. The ECG might demonstrate findings of pulmonary hypertension and right ventricular hypertophy.  Atrial fibrillation is not an uncommon finding among patients with mitral stenosis.
