Paroxysmal atrial fibrillation are episodes of atrial fibrillation, an irregular heart rhythm, that go away on their own. They may last anywhere from a few seconds to a few weeks and may not cause symptoms. Sometimes paroxysmal atrial fibrillation is related to other factors, such as alcohol use, stress, or activity.
