ABSTRACT:
The present invention is an external defibrillator 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 functions based on best-fit models are used to generate the waveforms. The waveforms are dynamically adjusted to compensate for changes in resistance due to changes in the voltage during delivery of the waveform. The waveforms include a first and a second phase and are formed with minimal delay therebetween.
