Stages of A-Fib

There are different types of atrial fibrillation. These distinctions are made because the treatment depends on the type of atrial fibrillation. One may also start out with paroxysmal A-Fib and over time progress to persistent  or long-standing persistent A-Fib

Paroxysmal: Refers to atrial fibrillation that comes and goes on its own. Episodes may last anywhere from a few minutes to several hours and sometimes days, but not lasting longer than 7 days. No medical treatment is needed to stop the episodes of atrial fibrillation.

Persistent: Atrial fibrillation episodes that last longer than 7 days. Also includes A-Fib lasting less than 7 days, but needing medicine or electrical cardioversion to stop the irregular rhythm.

Long-standing Persistent: Persistant atrial fibrillation that lasts longer than one year. Medicine and electrical cardioversion have failed and a normal heart rhythm cannot be restored without further intervention.
