(E) A defibrillator is used on a patient suffering from cardiac dysrhythmia, or irregular heart contractions. Once both pads are placed on the patient’s chest, electrical energy is transferred across the chest. This depolarizes the cardiac muscle and encourages the heart’s pacemaker to re-establish normal cardiac muscle contractions. Model the flow of electrical energy through the patient’s chest.
