Method and apparatus for remote detection and monitoring of functional chronotropic incompetence
First 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.

Abstract
Methods and apparatus to determine the presence of and track functional chronotropic incompetence (hereinafter “CI”) in an in-home setting under conditions of daily living. The functional CI of the patient may be determined with one or more of a profile of measured patient heart rates, a measured maximum patient heart rate, or a peak of the heart rate profile. The functional CI of the patient may be determined with the measured heart rate profile, in which the measured heart rate profile may correspond to heart rates substantially less than the maximum heart rate of the patient, such that the heart rate can be safely measured when the patient is remote from a health care provider. The functional CI of the patient may be determined based a peak of the remotely measured heart rate profile, for example a peak corresponding to the mode of the heart rate distribution profile.
