Atrial fibrillation (AF) is characterized by an irregularly irregular heart rhythm that may have a rapid ventricular response rate. Classification of AF begins with distinguishing a first detectable episode, irrespective of whether it is symptomatic or self-limited. AF is associated with increased morbidity and mortality, in part because of the risk for thromboembolic disease, particularly stroke, and in part because of its associated risk factors. Individuals in sinus rhythm typically live longer than individuals with AF.

Development of AF predicts heart failure and is associated with a worse New York Heart Association heart failure classification. AF may also worsen heart failure in individuals who are dependent on the atrial component of the cardiac output. Those with hypertensive heart disease and those with valvular heart disease are particularly at high risk of developing heart failure when AF occurs. In addition, AF may cause tachycardia-mediated cardiomyopathy if adequate rate control is not established.
