DUAL-MODULE MOTION DETECTION SYSTEM FOR THE POWER SAVING OF RATE ADAPTATION ALGORITHM IN A LEADLESS PACEMAKER

摘要

The present disclosure relates to an implantable cardiac pacemaker (1), wherein the pacemaker (1) is configured to apply pacing pulses to the heart of a person during operation of the pacemaker (1), and wherein the pacemaker (1) comprises a motion detection system that comprises a first module (10) and a second module (20), wherein the first module (10) is configured to continuously run during operation of the pacemaker (1), and wherein the second module (10) is configured to receive a trigger signal (S) to change from an idle state to an active state or to receive a further trigger signal (S') to change from an active state to an idle state, wherein an energy consumption per time unit of the second module (20) in the active state is larger than in the idle state, and wherein when the second module (20) is in its active state, the second module (20) is configured to execute a rate adaptation algorithm that adapts a rate of the pacing pulses to meet a metabolic demand of the person.
