Classification of atrial fibrillation (AF1). Either paroxysmal or persistent AF may be recurrent AF (AF2). Paroxysmal AF lasts 7 or fewer days and terminates spontaneously (AF3). Persistent AF includes cases of long-standing AF (eg, greater than 1 year), usually leading to permanent AF (AF4). Persistent AF does not terminate spontaneously, but requires electrical or pharmacological cardioversion to restore normal sinus rhythm; if the first-detected episode of AF does not terminate spontaneously, it is also designated persistent.
