Persistent atrial fibrillation means that episodes of the irregular heart rhythm last longer and often don't go away on their own. If an episode lasts more than 7 days, it is called persistent atrial fibrillation.
Treatment with medicine or cardioversion can restore a normal rhythm. This normal rhythm may last for several weeks or longer before atrial fibrillation happens again.
