1. An implantable device, comprising:

  • an implantable housing;

    a plurality of implantable electrodes coupled to the housing and configured for sensing cardiac electrical activity;

    detection circuitry provided in the housing and coupled to at least some of the plurality of electrodes, the detection circuitry producing a cardiac electrical signal in response to the sensed cardiac electrical activity;

    an implantable sensor configured to sense movement of a heart and produce a sensor signal in response to the sensed heart movement;

    sensor circuitry provided in the housing and coupled to the sensor, the sensor circuitry configured to produce an audio signal in response to the sensor signal;

    memory provided in the housing and coupled to the detection circuitry and sensor circuitry, the memory configured to store the audio signal and the cardiac electrical signal;

    a controller provided in the housing and coupled to the memory, detection circuitry, and sensor circuitry; and

    communications circuitry provided in the housing and coupled to the controller, the communications circuitry configured to telemeter the cardiac electrical signal and the audio signal to a patient-external device.
