Abstract
A cardiac pacemaker having circuitry for varying the pacing rate, in accordance with a signal recorded in the patient's body and correlated with the stroke volume, in which for automatic adaptation of the functional dependency of the pacing rate on the value correlated with the stroke volume at the maximum allowable or expected physical exertion on the part of the patient, the pacing rate is varied in a range adapted to this exertion; as a reference point for the functional dependency, the particular rate is associated with the particular stroke volume at which the product of the stroke volume and the pacing rate is a maximum.
