Abstract
A defibrillator for providing a constant low pulsed current to a patient's heart has a high voltage capacitor for storing electrical energy. An inductor connected to the capacitor smooths out the discharge curve and produces a low current low frequency defibrillator pulse supplied to a patient's heart. The pulse is usually biphasic.
