Abstract
The present invention discloses a method and device in which an external defibrillator is integrated with an algorithm implemented in a programmable microprocessor which controls and manages the formation of defibrillation waveforms. The waveforms are dynamically adjusted and created to be consistent with a myocardial cell response waveform. Dynamic tilt calculations based on time slices and corresponding fit functions based on best-fit models are used to generate the waveforms. The waveforms include a first and a second phase and are formed with minimal delay therebetween.
