摘要
Retroperfusion control apparatus (11) for supplying arterial blood of a patient to the venous side of the patient's heart including a pump (81) having an inlet (104) and an outlet (114) and a piston (88) movable through a pump stroke for moving a liquid from the inlet (104) to the outlet (114) of the pump (81). A stepper motor (47) is provided which drives the piston (81). Electronic circuitry is provided for driving the stepper motor (47) and senses the presence of an R wave in a patient to operate the stepper motor (47) in response to the sensed R wave.
