A trial fibrillation (AF) is the most common, clinically significant cardiac arrhythmia. It occurs when a diffuse and chaotic pattern of electrical activity in the atria suppresses or replaces the normal sinus mechanism, leading to deterioration of mechanical function. Atrial fibrillation is a major cause of morbidity, mortality, and health care expenditures; prevalence in the United States is 2.3 million cases and is estimated to increase to 5.6 million by the year 2050 (1). Atrial fibrillation is associated with a 5-fold increased risk for stroke and is estimated to cause 15% of all strokes (2). Independent of coexisting diseases, the presence of AF confers a 2-fold increased risk for all-cause mortality (3).
