Atrial Fibrillation - Treatment Overview
It's hard to say exactly what your treatment for atrial fibrillation will be, because it depends so much on your symptoms and your risk for other health problems.
Treatments are aimed at helping you feel better and preventing future problems, especially stroke and heart failure. There are three main types of treatment:
Treatment to slow your heart rate
Rate-control medicines are used if your heart rate is too fast.
They usually do not return your heart to a normal rhythm-in other words, your heartbeat will still be irregular. But these medicines can keep your heart from beating at a dangerously fast rate. These medicines may also relieve symptoms.
Treatment to control your heart rhythm
Treatment to control your heart rhythm is done to try to stop atrial fibrillation and keep it from returning. It may also help your symptoms. Treatments include:
- Rhythm-control medicines, also called antiarrhythmics.
Electrical cardioversion. This procedure uses a low-voltage electrical shock to return the heart to a normal rhythm.

Catheter ablation. This minimally invasive procedure destroys tiny areas in the heart that cause atrial fibrillation. It can relieve symptoms and improve quality of life.
- Atrial Fibrillation: Should I Have Catheter Ablation?
AV node ablation is another type of catheter ablation. It does not stop atrial fibrillation, but it can relieve symptoms.
Maze procedure. This may be done as a minimally invasive surgery or during open-heart surgery. It creates scar tissue that blocks excess electrical impulses from traveling through your heart.
Treatment to prevent stroke
Atrial fibrillation is dangerous because if the heartbeat isn't strong and steady, blood can collect, or pool, in the atria . And pooled blood is more likely to form clots. Clots can travel through the bloodstream to the brain and other areas such as the legs. If clots travel to the brain, they can block blood flow and cause a stroke.
Your doctor can help you know your risk of a stroke based on your age and health. This information can help you and your doctor decide how to lower your risk.
If you are at an average-to-high risk of having a stroke, your doctor may prescribe long-term use of an anticoagulant medicine, such as warfarin, to lower this risk.
If you are at low risk of having a stroke or you cannot take an anticoagulant, you may choose to take daily aspirin or to not take a blood thinning medicine.
