1. A pacemaker comprising:

  • the pacemaker configured as a leadless cardiac pacemaker comprising;

    a housing;

    a plurality of electrodes coupled to the housing;

    a pulse delivery system hermetically contained within the housing and electrically coupled to the electrode plurality, the pulse delivery system configured for sourcing energy internal to the housing comprising a pulse generator that generates electrical pulses operative for cardiac stimulation by the plurality of electrodes and encoded for conveying information signals to a device external to the pacemaker by the plurality of electrodes;

    an activity sensor hermetically contained within the housing and adapted to sense activity; and

    a processor hermetically contained within the housing andcommunicatively coupled to the pulse delivery system, the activity sensor, and the electrode plurality, the processor configured to control leadless electrical pulse delivery at least partly based on the sensed activity.
