Abstract
A control circuit for controlling a pump speed of a blood pump implanted in a patient including a processor in communication with the implanted blood pump, the processor having processing circuitry configured to reduce a pump speed relative to a standard set speed based on a timing of a systole phase of the patient, the systole phase including a first segment during which a ventricular pressure is at its greatest and a second segment occurring after the first segment during which the ventricular pressure is at its lowest, the pump speed being reduced during the second segment.
