Synchronized cardioversion is a LOW ENERGY SHOCK that uses a sensor to deliver electricity that is synchronized with the peak of the QRS complex (the highest point of the R-wave). When the “sync” option is engaged on a defibrillator and the shock button pushed, there will be a delay in the shock.

Where in the rhythm is the shock delivered in synchronized cardioversion?

Defibrillation. Synchronized cardioversion involves the delivery of a low-energy shock which is timed or synchronized to be delivered at a specific point in the QRS complex (see the image below). A synchronized shock is delivered at this precise moment to avoid causing or inducing ventricular fibrillation.

What is Synchronised DC cardioversion?

Synchronized electrical cardioversion is a medical procedure in which an electric current is passed through a person's chest to convert abnormal heart rhythm (arrhythmia) to normal heart rhythm.
