WebFeb 26, 2024 · Biphasic waveforms (mild) Artery walls lose elasticity as they become diseased, which is reflected in a loss of humps in the ABI waveforms. Audible biphasic waveforms only have two sounds, and visually (e.g., on analog) have only one peak and one pit. Notably, biphasic waveforms still have a sharp upstroke to the tallest peak. WebMethods: We prospectively and randomly compared the defibrillation efficacy of a 50% and a 65% tilt asymmetric biphasic waveform using the unipolar defibrillation system in 15 consecutive cardiac arrest survivors prior to implantation of a presently available standard transvenous defibrillation system. The RV defibrillation electrode has a 5-cm ...
