paroxysmal atrial fibrillation definition
Atrial fibrillation (AF) is the most common arrhythmia, affecting more than 4% of the population over the age of 60. 1,2 AF can be divided into permanent and paroxysmal atrial fibrillation (PAF). PAF is defined as at least two separate episodes of AF that terminate spontaneously in less than 7 days, usually within 24 hours. 3 These episodes of AF last greater than 30 seconds and are not related to a reversible cause.
