A heart stimulator which delivers stimulation pulses to a heart when the heart's spontaneous rate (1) drops below a defined basic rate (4) is described. In order to reduce the period (STIM) during which the heart stimulator emits stimulation pulses, the defined basic rate (4) is slow. When the spontaneous heart rate (1) drops below the defined basic rate (4), stimulation pulses are initially emitted at a faster stimulation rate (5), in relation to the basic rate, which then drops towards the defined basic rate (4). <IMAGE> |
