A heart stimulator emits stimulation pulses to a heart, and has a regulator unit for regulating a variable function in the heart stimulator, a measurement device for measuring the return flow of blood to the heart, and a control device for controlling the regulation of the function by the regulator unit on the basis of changes in the return flow of blood. The regulator unit may be a pulse generator which generates and emits the stimulation pulses at a variable interval, the heart stimulator then becoming rate-adaptive and optimizing cardiac output. In this manner, heart rate is regulated on the basis of a variable directly related to the body's oxygenation needs.
