Atrial fibrillation and flutter

Alternative names:

auricular fibrillation

Treatment:

Treatment varies depending on the cause of the atrial fibrillation or flutter. Medication may include digitalis or other medications that slow the heart beat or that slow conduction of the impulse to the ventricles.

Electrical cardioversion may be required to convert the arrhythmia to normal (sinus) rhythm.

Expectations (prognosis):

The disorder is usually controllable with treatment. Atrial fibrillation may become a chronic condition. Atrial flutter is usually a short-term problem.

Complications:

• incomplete emptying of the atria which can reduce the amount of blood the heart can pump
• emboli to the brain (stroke) or elsewhere--rare

Calling your health care provider:

Call your health care provider if symptoms indicate atrial fibrillation or flutter may be present.
