In medicine, pulsus bisferiens, or biphasic pulse, is a sign where, on palpation of the pulse, a double peak per cardiac cycle can be appreciated. Biphasic means striking twice. Classically, it is detected when aortic insufficiency exists in association with aortic stenosis, but may also be found in isolated but severe aortic insufficiency, and hypertrophic obstructive cardiomyopathy.

For IPGs that are long compared to PD, the biphasic pulse becomes nearly as efficient as a non-charge-balanced monophasic pulse for eliciting threshold responses in cochlear nerve stimulation [ 47, 49 ]. However, IPG variation seems to only exhibit a minor effect on loudness perception [ 46, 48, 50 ].

Nov 03, 2008 · Pulse generator. The "Chemopulse" is built up by a toroidal core transformer generating a roughly rectangular pulse which is split in two halves that are sequentially driven to obtain a biphasic pulse. The pulses are not singularly produced but are created in bursts of eight, thus reducing the treatment time and the overall patient morbidity.
