Description: This 3D animation depicts an abnormal heart rhythm, and how normal heart rhythm 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.
