Biphasic waveform external defibrillation thresholds for spontaneous ventricular fibrillation secondary to acute ischemia.
OBJECTIVES The goal of this study was to determine if the defibrillation threshold (DFT) after spontaneous ventricular fibrillation (VF) secondary to acute ischemia differs from the DFT for electrically induced VF in the absence of ischemia in anesthetized, closed-chest dogs and pigs. BACKGROUND The efficacy of external defibrillators has been tested mainly in animals and humans using E-VF, y...
متن کاملResuscitation after prolonged ventricular fibrillation with use of monophasic and biphasic waveform pulses for external defibrillation.
BACKGROUND Survival after prolonged ventricular fibrillation (VF) appears severely limited by 2 major factors: (1) low defibrillation success rates and (2) persistent post-countershock myocardial dysfunction. Biphasic (BP) waveforms may prove capable of favorably modifying these limitations. However, they have not been rigorously tested against monophasic (MP) waveforms in clinical models of ex...
متن کاملA comparison of biphasic and monophasic waveform defibrillation after prolonged ventricular fibrillation.
STUDY OBJECTIVE To compare the effects of biphasic defibrillation waveforms and conventional monophasic defibrillation waveforms on the success of initial defibrillation, postresuscitation myocardial function, and duration of survival after prolonged duration of untreated ventricular fibrillation (VF), including the effects of epinephrine. DESIGN Prospective, randomized, animal study. SETTI...

متن کاملComparison of a novel rectilinear biphasic waveform with a damped sine wave monophasic waveform for transthoracic ventricular defibrillation. ZOLL Investigators.
OBJECTIVES We compared the efficacy of a novel rectilinear biphasic waveform, consisting of a constant current first phase, with a damped sine wave monophasic waveform during transthoracic defibrillation. BACKGROUND Multiple studies have shown that for endocardial defibrillation, biphasic waveforms have a greater efficacy than monophasic waveforms. More recently, a 130-J truncated exponential...
