Are There Different Types of Atrial Fibrillation?

Early in the disease, Atrial Fibrillation is often intermittent, meaning that it can come and go without warning. There may also be long spells between ‘episodes’. In fact, some people in this early stage of AF may not even be aware they have it.
AF falls into three categories, which also help to describe the progression of the disease.

  1. Paroxysmal AF – multiple episodes that cease within 7 days without treatment;
  2. Persistent AF – episodes lasting longer than 7 days, or less when treated;
  3. Longstanding persistent AF – continuous AF which has occurred for more than one year.
