This divergence may be attributed to the different electrophysiological approaches used in the present study compared to the previous studies: fiber versus cortical stimulation; freely behaving versus acute anesthetized animals; and triphasic versus monophasic waveforms of evoked responses.
The American heart association recommends 360J for the monophasic waveform and 200J for the biphasic waveform just for the sake of ease and to prevent unnecessary delays in selection of the joules.
VIENNA -- Juicing up automatic external defibrillators by utilizing biphasic instead of the traditional monophasic waveforms results in a higher shock success rate, Dr.
50%-99% diameter reduction Monophasic waveform with loss of reverse flow component and forward flow throughout cardiac cycle; extensive spectral broadening; peak systolic velocity is increased > 100% relative to adjacent proximal segment; distal waveform is monophasic, with reduced systolic velocity Occlusion No flow detected within imaged arterial segment preocclusive " thump" may be heard just proximal to site of occlusion; distal waveform are monophasic, with reduced systolic velocities.
