This study compares transvenous electrode catheters' defibrillation effectiveness when using the trapezoidal waveform and when using the damped half-sinusoidal waveform, at comparable energy levels. Five greyhounds were used in some 272 fibrillation/defibrillation trials. Neither total energy, peak current, nor peak voltage could be absolutely correlated with percent effectiveness for transvenous defibrillation. However, for a given waveform, an increase in delivered energy was associated with a large and statistically significant increase in percent success.
本研究比较了在能量水平相当的情况下，使用梯形波形和阻尼半正弦波形时经静脉电极导管的除颤效果。在约272次颤动/除颤试验中使用了5只灵缇犬。对于经静脉除颤，总能量、峰值电流和峰值电压均与除颤成功率无绝对相关性。然而，对于给定波形，输送能量的增加与成功率的大幅且具有统计学意义的提高相关。
