Electrode system influence on biphasic waveform defibrillation efficacy in humans.
BACKGROUND Several clinical studies have demonstrated a general superiority of biphasic waveform defibrillation compared with monophasic waveform defibrillation using epicardial lead systems. To test the breadth of utility of biphasic waveforms in humans, a prospective, randomized evaluation of defibrillation efficacy of monophasic and single capacitor biphasic waveform pulses was performed for...
متن کاملOptimization of biphasic waveforms for human nonthoracotomy defibrillation.
BACKGROUND Biphasic waveforms reduce defibrillation threshold (DFT) in a wide variety of models. Although there are several human studies of long-duration, high-tilt biphasic waveform defibrillation, the specific biphasic waveform shape required to achieve optimal DFT reduction is unknown. METHODS AND RESULTS This study tested the effect of single capacitor biphasic waveform tilt modification...
متن کاملEffect of pulse separation between two sequential biphasic shocks given over different lead configurations on ventricular defibrillation efficacy.
BACKGROUND Two sequential biphasic shocks delivered over separate lead configurations markedly improve defibrillation efficacy compared with a single shock alone. We investigated the effect of varying the intershock interval between sequential biphasic shocks on defibrillation. METHODS AND RESULTS Defibrillation thresholds (DFTs) were obtained in six dogs for shock separations ranging from 0....

Background. Several clinical studies have demonstrated a general superiority of biphasic waveform defibrillation compared with monophasic waveform defibrillation using epicardial lead systems.

متن کاملA prospective randomized evaluation of biphasic versus monophasic waveform pulses on defibrillation efficacy in humans.
Biphasic waveforms have been suggested as a superior waveform for ventricular defibrillation. To test this premise, a prospective randomized intraoperative evaluation of defibrillation efficacy of monophasic and biphasic waveform pulses was performed in 22 survivors of out of hospital ventricular fibrillation who were undergoing cardiac surgery for implantation of an automatic defibrillator. Th...
