Atrial Fibrillation. Atrial fibrillation causes a rapid, disorganized, and uncoordinated twitching of atrial musculature. It is the most common dysrhythmia that causes patients to seek medical attention. It may start and stop suddenly. Atrial fibrillation may occur for a very short time (paroxysmal), or it may be chronic. Atrial fibrillation is usually associated with advanced age, valvular heart disease, coronary artery disease, hypertension, cardiomyopathy, hyperthyroidism, pulmonary disease, acute moderate to heavy ingestion of alcohol (“holiday heart” syndrome), or the aftermath of open heart surgery. Sometimes it occurs in people without any underlying pathophysiology (termed lone atrial fibrillation).
