Atrial Fibrillation (Abbreviated Version) - Medical Animation
This 3D medical animation depicts a condition referred to as atrial fibrillation. It 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.
