Upon confirmation of synchronization, the shock is delivered, often resulting in an audible click and the immediate observation of a restored rhythm on the monitor. Unlike defibrillation, which is delivered without synchronization to the cardiac cycle, cardioversion is synchronized to the R-wave of the ECG to avoid inducing ventricular fibrillation during the vulnerable T-wave phase.

By delivering a shock during the synchronized phase, clinicians aim to stop the re-entrant circuits or chaotic firing that causes arrhythmias such as atrial fibrillation or unstable supraventricular tachycardia. Anticoagulation is often required prior to the procedure to mitigate the risk of stroke caused by dislodged clots.
Sedation is typically administered to minimize discomfort, although in emergency scenarios where the patient is unconscious or critically unstable, sedation may be omitted. Defibrillator cardioversion represents a critical intervention in emergency medicine, designed to restore a chaotic, ineffective heart rhythm to a stable, normal pattern.

The defibrillator synchronizes to the R-wave, and the clinician selects the appropriate energy level, often starting with 50 to 100 joules for atrial arrhythmias and higher doses for ventricular tachycardia. This procedure utilizes a precisely timed electrical shock to interrupt the chaotic electrical activity of conditions like ventricular fibrillation or pulseless ventricular tachycardia.
