1. A method for emulating a surface electrocardiogram (EKG) of a patient in which an implantable cardiac stimulation device is implanted, the method comprising:

  • sensing first and second cardiac signals using electrodes implanted within the patient;

    identifying a pair of baseline points in each of the first and second cardiac signals;

    selectively concatenating that portion of the first cardiac signal that lies between the pair of baseline points with that portion of the second cardiac signal that lies outside the pair of baseline points, using the baseline points as concatenation points to generate an emulated surface EKG using the implantable device;

    transmitting the emulated surface EKG to an external relay device; and

    relaying the emulated surface EKG to a remote monitor using the external relay device.
