Arrhythmias in the natural history of mitral stenosis.

Mitral stenosis with or without regurgitation is the most common form of valve disease associated with arrhythmias, as atrial fibrillation (AF) is the most frequent complication of mitral stenosis. AF may occur as transient episodes with the patients reporting a history of palpitation, paroxysmal dyspnea or tachycardia or as sustained arrhythmia.
