For other people, atrial fibrillation doesn't go away on its own. If this happens, treatment can help your heartbeat get back to normal.

It's possible to get atrial fibrillation again from time to time. In some people, it can be permanent. If you get permanent atrial fibrillation, you may need to take pills regularly to control your heartbeat.

Some people who have atrial fibrillation get complications. Blood clots may form in the heart because blood isn't flowing normally through it. These clots can get into the bloodstream, where they can block important blood vessels. When this happens it is called thromboembolism.

If one of these blood clots blocks an artery to the brain it can cause a stroke, but drug treatment can be given to prevent these clots.

If no treatment is given to prevent blood clots, then between 1 in 20 and 1 in 30 people with atrial fibrillation will have a stroke. Your risk of a stroke is affected by lots of things. Things that increase your risk include being older, having high blood pressure, or having a long-term medical condition, such as diabetes.
