Automatic External Defibrillation Monitoring in Cardiac Arrest

In case of cardiac arrest caused by shockable rhythms the automatic external cardioverter defibrillator (AECD) will automatically deliver defibrillation. Automated External Cardioverter Defibrillator (AECD; The PowerHeart CRM, Cardiac Science Inc., Seattle, WA) is a device attached to the chest wall by pads, monitors the electrocardiogram, and is capable of automatically delivering electric countershock to appropriate rhythms without operator intervention. The device will deliver only one shock of 150 Joules for pulseless ventricular tachycardia and ventricular fibrillation.
