Abstract
A medical electronic diagnostic device particularly suitable for determining and displaying segmental pulsatile flow of a patient. Means are provided for stabilization of a calibrated segmental volume time curve relative to a baseline, so as to eliminate the effect of patient movement during testing, as well as miscellaneous electrical noise. The disclosed device is capable, in addition to displaying a pulse volume curve, of measuring and recording the pulsatile component of the total blood flow.
