Description: This 3D medical animation shows what happens during atrial fibrillation, the risks associated with having atrial fibrillation and the common treatments for atrial fibrillation. Atrial fibrillation is a type of arrhythmia, which is an abnormality in the pace or force of your heartbeat. If you have atrial fibrillation, the heart’s upper chambers contract in a fast, twitchy fashion, resulting in an irregular, uncoordinated heartbeat.
