Atrial fibrillation (AFib) is a type of irregular or rapid heartbeat (arrhythmia). In AFib, 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.
