Provided is an artificial heart control device 60 for controlling a blood pump which assists flow of blood in a heart, the artificial heart control device 60 including: a timing detection part 80 which is configured to detect reference timing within a cardiac cycle of the heart; and a blood pump control part 62 which is configured to control a rotational speed of the blood pump, wherein the blood pump control part 62 controls, with reference to the reference timing detected by the timing detection part 80, the rotational speed of the blood pump such that the rotational speed becomes a rotational speed corresponding to a predetermined control pattern. According to the present invention, it is possible to provide an artificial heart control device, an artificial heart system and an artificial heart control method which can provide a load control optimum for the recovery of functions of a patient's own heart.
