Comparative Study
Direct comparison of monophasic, biphasic and sequential pulse defibrillation over a single current pathway.
Defibrillation waveform and its spatial and temporal distribution are important determinants of its efficacy. Previous comparisons of monophasic, biphasic and sequential waveforms have used one current pathway for monophasic and biphasic defibrillation and two pathways for sequential defibrillation thus confounding a direct comparison of the waveforms. ⋯ Biphasic pulses are superior to monophasic or sequential pulses delivered over a single current pathway.
