Detection of chronotropic incompetence

An apparatus for detecting chronotropic incompetence, comprising:

• a first sensor configured to generate first sensor data;
• a second sensor configured to generate second sensor data;
• a memory configured to store the first and second sensor data and a baseline cardiac health measure;
• and
• a processor, coupled to the memory and the first sensor and the second sensor, wherein the processor is configured to:
• in response to receiving a user input specifying an estimate of activity level for the user, determine the baseline cardiac health measure for the user from the memory, wherein the baseline cardiac health measure includes a baseline validation factor for the user and corresponds to the estimate of activity level for the user;
• determine a validation factor for the user from first sensor data generated by a first sensor, wherein the first sensor data corresponds to a same time period as the estimate of activity level for the user;
• validate the estimate of activity level for the user with the validation factor by comparing the validation factor with the baseline validation factor;
• determine a cardiac health measure for the user from second sensor data generated by a second sensor corresponding to the same time period;
• compare the cardiac health measure for the user with the baseline cardiac health measure;
• and
• provide a signal indicating chronotropic incompetence for the user based upon the comparison of the cardiac health measure for the user with the baseline cardiac health measure.

A computer program product comprising a computer readable storage medium having program code stored thereon, the program code executable by a processor to perform operations for detecting chronotropic incompetence comprising:

• in response to receiving a user input specifying an estimate of activity level for the user, determining a baseline cardiac health measure for the user from a memory, wherein the baseline cardiac health measure includes a baseline validation factor and corresponds to the estimate of activity level for the user;
• determining a validation factor for the user from first sensor data generated by a first sensor, wherein the first sensor data corresponds to a same time period as the estimate of activity level for the user;
• validating the estimate of activity level for the user with the validation factor by comparing the validation factor with the baseline validation factor;
• determining a cardiac health measure for the user from second sensor data generated by a second sensor corresponding to the same time period, wherein the first and second sensors are coupled to the processor;
• comparing the cardiac health measure for the user with the baseline cardiac health measure;
• and
• providing a signal indicating chronotropic incompetence for the user based upon the comparing of the cardiac health measure for the user with the baseline cardiac health measure.

A method of detecting chronotropic incompetence, comprising:

• determining, using a processor, an estimate of activity level for a user from first sensor data generated by a first sensor;
• determining, using the processor, a baseline cardiac health measure for the user from a memory, wherein the baseline cardiac health measure includes a baseline validation factor for the user and corresponds to the estimate of activity level for the user;
• determining, using the processor, a validation factor for the user from second sensor data generated by a second sensor, wherein the second sensor data corresponds to a same time period as the estimate of activity level for the user and the first sensor data;
• validating the estimate of activity level for the user with the validation factor by comparing the validation factor with the baseline validation factor;
• determining a cardiac health measure for the user from third sensor data generated by a third sensor corresponding to the same time period, wherein the first, second, and third sensors and the memory are coupled to the processor;
• comparing, using the processor, the cardiac health measure for the user with the baseline cardiac health measure;
• and
• providing, using the processor, a signal indicating chronotropic incompetence for the user based upon the comparing of the cardiac health measure for the user with the baseline cardiac health measure.
