What is atrial fibrillation? (AF)

Atrial Fibrillation is an irregular heart rate that affects the upper chambers of the heart (atria). It prevents blood from being pumped efficiently to the rest of your body.

Atrial Fibrillation Rhythm

Types of atrial fibrillation (A.F.)


Comes and goes. It stops on its own.
It occurs from minutes to days.
In this stage, AF has more options for treatment.

It lasts for more than a week.
It will not stop on its own.
It can become permanent.
Treatment options are less than with paroxysmal AF

Continuous atrial fibrillation; the heart cannot return to its normal rhythm. Treatment options are very limited

What are the causes of ATRIAL FIBRILLATION? (A.F.)

The causes of AF are often unclear. In some cases, AF may be the result of:

  • Heart abnormality from birth
  • Damage to the heart structure from a previous heart attack
  • Heart valve problems
  • Aging process (elderly patients have more AF)
  • Atrial size (bigger atria have more chance of developing AF)

People with otherwise normal hearts may also develop AF.
