1. An apparatus comprising:

  • a data input circuit configured to receive a cardiac activity signal of a patient, the cardiac activity signal including information about intrinsic and non-intrinsic cardiac activity;

    a memory circuit configured to store information about the received cardiac activity signal; and

    a processor circuit, coupled to the memory circuit, the processor circuit configured to;

    determine a heart rate variability using the stored information about the cardiac activity signal including information about intrinsic and non-intrinsic cardiac activity; and

    determine a rate-responsive pacing mode suitability indication for the patient using the determined heart rate variability.
