Abstract
An implantable cardiac pacemaker, wherein the pacemaker is configured to apply pacing pulses to the heart of a person during operation of the pacemaker, and wherein the pacemaker comprises a motion detection system that comprises a first module and a second module. The first module is configured to continuously run during operation of the pacemaker. The second module is configured to receive a trigger signal to change from an idle state to an active state or to receive a further trigger signal to change from an active state to an idle state. An energy consumption per time unit of the second module in the active state is larger than in the idle state. When the second module is in its active state, the second module is configured to execute a rate adaptation algorithm that adapts a rate of the pacing pulses to meet a metabolic demand of the person.
