Claim:
1. An apparatus to monitor a patient, the apparatus comprising, a processor system comprising at least one processor having a tangible medium with instructions of a computer program embodied thereon, the processor system configured to: receive heart rate data of the patient, the heart rate data comprising a plurality of measurements of the patient's heart rate taken over a period of time by an adherent and/or implantable device associated with the patient without subjecting the patient to a cardiac stress test; construct a heart rate profile based on the plurality of measurements taken over a period of time, wherein a peak of the heart rate profile is selected as representative of the resting heart rate of the patient, the peak of the heart rate profile corresponding with a mode of the plurality of measurements; determine an age-corrected maximum heart rate of the patient based on patient age; determine a heart rate reserve (HRR) based on the age corrected maximum heart rate and resting heart rate of the patient; and compare the HRR to a threshold value and identify chronotropic incompetence if the HRR is below the threshold.
