Description

The conversion of an arrhythmia (abnormal heart rhythm), such as Atrial fibrillation, to a sinus (normal) rhythm, using an electrical defibrillator or by pharmacological means.

In synchronised electrical cardioversion, the patient is anaesthetised, defibrillator pads are placed on the patient, and a shock is delivered to the myocardium - synchronously with an ECG R-wave.
