Atrial Fibrillation

What is atrial fibrillation

Atrial fibrillation 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 notice heart palpitations or chest pain. Blood also pools in your heart, which increases your risk of forming clots and can leads to strokes or other complications.can also occur without any signs or symptoms. Untreated fibrillation can lead to serious and even life-threatening complications.

Sometimes goes away on its own. For some people 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.
