Atrial fibrillation is a type of irregular or rapid heartbeat (arrhythmia). In atrial fibrillation, the top part of the heart (atria) beats in an irregular pattern. This makes the heart unable to pump blood normally and effectively.
The goal of treatment is to prevent blood clots from forming, control your heart rate, or restore your heartbeat to a normal rhythm. If this condition is not treated, it can cause serious problems, such as a weakened heart muscle (cardiomyopathy) or a stroke.
In some cases, the cause of this condition is not known.
In some cases, there are no symptoms.
In some cases, underlying conditions will be treated.
These symptoms may represent a serious problem that is an emergency. Do not wait to see if the symptoms will go away. Get medical help right away. Call your local emergency services (911 in the U.S.). Do not drive yourself to the hospital.
