Conference paper


Atrial fibrillation (AF) is considered one of the most common clinically relevant cardiac arrhythmias. The prevalence of AF increases with age and is reported to be 0.2%–0.3% at age 25 – 35 years, 3%–4% at age 55 – 64 years, and 5%–9% at age 62 – 90 years (1). AF is usually a consequence of heart disease involving the left atrium, but may also result from extracardiac conditions such as hyperthyroidism, surgery, acute alcohol intoxication, cholinergic drug use, or diagnostic procedures. In a minority of patients, no contributing factors or overt heart disease can be identified (lone AF). In most cases the clinical and hemodynamic consequences of AF are related to the severity of underlying heart disease.
