A first-order time constant model of the heart demonstrates that for biphasic waveforms, a region of reliable low threshold defibrillation exists with phase 1/phase 2 durations from 3.5/1.5 to 9/6 ms.

Model suggests biphasic waveform optimization; leaves open prospective clinical validation before practice impact.
A conceptual model of defibrillation identifies optimal phase durations for biphasic waveforms to achieve reliable low threshold defibrillation.
B. G. Cleland (1996) studied Defibrillation. Defibrillation waveforms was evaluated on Threshold voltage for defibrillation. A first-order time constant model of the heart demonstrates that for biphasic waveforms, a region of reliable low threshold defibrillation exists with phase 1/phase 2 durations from 3.5/1.5 to 9/6 ms.
