Abstract :
A control system employing two adjustable reservoirs for the independent regulation of atrial and/or arterial blood pressures simultaneously at both sides of the heart is described. Two servo-motors position these reservoirs and thereby automatically regulate atrial filling and hence ventricular output to produce various controlled pressure wave forms.
