Man clutching his chest Atrial fibrillation, also known as A-fib or AF, is one of the most common types of arrhythmias, which are irregular heart rhythms. Atrial fibrillation causes your heart to beat much faster than normal. Also, your heart’s upper and lower chambers do not work together as they should. When this happens, the lower chambers do not fill completely or pump enough blood to your lungs and body. This can make you feel tired or dizzy, or you may feel like your heart is skipping a beat, fluttering, pounding, or beating too hard or fast. You may also feel chest pain. Blood may pool in your heart, which increases your risk of forming clots and can lead to strokes or other complications. Atrial fibrillation can also occur without any symptoms. Untreated atrial fibrillation can lead to serious and even life-threatening complications.

Sometimes atrial fibrillation goes away on its own. For some people, atrial fibrillation is an ongoing heart problem that lasts for years. Over time, it may happen more often and last longer. Treatment restores normal heart rhythms, helps control symptoms, and prevents complications. Your doctor may recommend medicines, medical procedures, and lifestyle changes to treat your atrial fibrillation.
