Abstract
An implantable heart pacemaker includes a detector for natural heart muscle contractions in the region of the atrium and circuitry for stimulating heart muscle contractions in the region of the ventricle, the stimulating circuitry generating a stimulating pulse following the detection of a natural heart muscle contraction in the region of the atrium. The repetition rate of the pulses which stimulate heart muscle contractions in the region of the ventricle is limited to a maximum value which tracks and is not less than the heartbeat frequency adapted to the current physical activity of the pacemaker user.
