ABSTRACT:
A method and apparatus for automatically controlling heart-synchronized circulating pumps; which method comprises obtaining the parameters needed for regulation by analyzing the blood pressure beat for beat and continuously regulating the pump by reference to the transient parameters thus obtained. An electrocardiogram (EKG) is taken and analyzed, the immediate past history of the heart beat is derived from the analysis and a calculation used to determine the control action exerted on a heart pump. The control action is exerted on the pump through the control action calculator. Thus the body of the patient is included in a closed regulating cycle.
