The efficacy of trapezoidal wave forms for ventricular defibrillation.
The purpose of this study was to evaluate the efficacy of a trapezoidal wave form for ventricular difibrillation. Overall efficacy showed the trapezoidal waveform to be effective for defibrillation, including patients weighing over 100 kg (220 lb). We concluded that (1) the trapezoidal waveform is an effective defibrillatory pulse and (2) the trapezoidal waveform offers pulse characteristics less deleterious than other established waveforms.
