Adaptive defibrillator design

Defibrillators are medical equipments which are widely used to resume the normal pacemaking activities of the heart in patients with myocardivim abnormalities. Electrical defibrillation is usually achieved by passing an electrical current pulse transthoracically through the heart of the patient. The source of this electrical current is usually a high voltage capacitor. The successful operation of defibrillators depends on two parameters, Transthoracic Resistance (TTR) and the peak defibrillation current. So far, control of this peak current during defibrillation by measurement and adjustment of the TTR has not been attempted (adaptive defibrillation). In this thesis, a method is described for implementing such an adaptive defibrillator by control of the defibrillator current.
