1. A system, comprising:

  • a context detector circuit configured to detect contextual condition associated with a patient, the contextual condition including information indicative or correlative of a change in metabolic demand of a patient;

    a heart rate (HR) analyzer circuit configured to sense from the patient a cardiac activity signal, extract a HR feature from the sensed cardiac activity signal, and perform a plurality of measurements of the HR feature in response to the detected patient contextual condition meeting a specified criterion;

    a target event indicator generator circuit configured to calculate one or more signal metrics using the plurality of measurements of the HR feature; and

    a physiologic event detector circuit coupled to the target event indicator generator circuit, the physiologic event detector circuit configured to detect a target physiologic event using the one or more signal metrics.
