- Atrial Fibrillation: Cardioversion - animation.

Atrial Fibrillation: Cardioversion (animation.)

This 3D animation shows how an abnormal heart rhythm, such as atrial fibrillation (a-fib or afib), can be restored with electrical cardioversion. 

This animation shows normal heart rhythm with electrical signals that originate at the SA node. A heart with abnormal signals and atrial fibrillation is shown forming a blood clot which results in a stroke.

 Next, the steps of the cardioversion procedure are illustrated: the placement of EKG electrodes, the placement of cardioversion paddles, the delivery of shock to the chest and heart, and the restoration of normal electrical signals within the heart.
