An artificial heart assembly may be provided with a blood inlet conduit adapted to be implanted within a subject, a blood outlet conduit adapted to be implanted within the subject, a pumping mechanism implanted within the subject that pumps blood from the blood inlet conduit to the blood outlet conduit, and a motor coupled to drive the pumping mechanism. The artificial heart apparatus has a power source and a control circuit operatively coupled to cause the motor to drive the pumping mechanism in a regular mode when the power source has a relatively high charge level and in an irregular mode when the power source has a relatively low charge level so that the subject can feel when the pumping mechanism is being driven in the irregular mode and thus know that the power source has the relatively low charge level. |
