DEFIBRILLATION

Written by

If a heart is fibrillating (see VENTRICULAR FIBRILLATION), the application of a large electric shock via paddles applied to the chest wall causes simultaneous electrical depolarisation of all the cardiac cells, and may allow the heart’s natural pacemaker to re-establish sinus rhythm. One paddle is placed below the right clavicle and the other over the cardiac apex. Care must be taken that no one is in contact with the patient or the bed when the shock is given, to avoid electrocution.
