Abstract: The invention is directed to an artificial heart having a pump, first and second pair of switching valves, and an electronic control unit which is arranged to control the valves to be actuated synchronously. When one of the first pair of valves and one of the second pair of valves are actuated to open, while the rest of them close, a blood from a right atrium is sucked and released by a pump through one of the first pair of valves, and subsequently, supplied into a pulmonary artery through one of the second pair of valves. At this time, a left atrium and an aorta are shut off, since the other ones of the first and second pair of valves are closed. Whereas, when the other ones of the first and second pair of valves are actuated to open while the rest of them close, the blood from the left atrium is sucked and released by the pump through the other of the first pair of valves, and subsequently, supplied into the aorta through the other of the second pair of valves.
