Temporal configuration of a motion sensor in an implantable medical device

An implantable medical device adapted for implantation within the heart of a patient and comprising:

• a plurality of electrodes adapted for one or more of sensing electrical cardiac activity and delivering therapy;
• a motion sensor for detecting movement of the patient;
• and
• a processing module configured to receive signals from the motion sensor and from the plurality of electrodes to determine patient status, wherein the processing module is configured to enhance the operation of the device by:
• determining that a predetermined event has occurred in the heart of the patient;
• and
• waiting a predetermined period of time after the predefined event and sampling an output of the motion sensor after the predetermined period of time has expired.
