Defibrillation - defibrillation refers to passing an electrical current across myocardium to depolarise the muscle, in order to convert a dysrhythmia back into normal sinus rhythm. It is the treatment for immediately life-threatening arrhythmias with which the patient does not have a pulse, ie ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT).1
