1. A method for communicating information between first and second implantable medical devices implanted within a patient, the method comprising:

  • generating a therapeutic electrical stimulation pulse using the first device, the stimulation pulse encoded with information to be communicated to the second device;

    delivering the encoded therapeutic stimulation pulse to patient tissue in a first heart chamber;

    detecting a far-field version of the therapeutic stimulation pulse within tissues of a second chamber of the patient'"'"'s heart using the second device; and

    decoding the detected pulse using the second device to extract the encoded information.
