Abstract: A cardiac care system integrated with a vehicle is provided wherein regularly included vehicle components are used in the system, where available. The cardiac care system includes an automated external defibrillator integrated with the vehicle so as to be readily available when needed. The vehicle battery is shared with the defibrillator to charge the defibrillation capacitor. A connector in the passenger compartment of the vehicle makes high voltage from the capacitor available inside the vehicle. Instructions are broadcast by the computer controlling the defibrillator over the regularly included vehicle speakers. A wireless communication system connecting the cardiac care system to outside help may be included.
