Determining Resting Heart Rate Using Wearable Device
A wearable device is described. The wearable device comprises: a device body configured to be secured in contact with a subject; a first sensor borne by the device body that is activatable to measure a heart rate of the subject; and control logic configured to activate the first sensor during a monitoring period during which the subject is determined to be in a sleep period.

- 1. A computer-implemented method for determining a minimum heart rate, comprising:
initializing a current minimum heart rate result; and for each of a plurality of sampling periods when a wearer of a wearable device is asleep:
obtaining via the wearable device a sequence of heart rate samples for the wearer;
assessing whether a threshold percentage of the heart rate samples is usable; and
if at least the threshold percentage of the heart rate samples is assessed to be usable:
aggregating the heart rate samples assessed to be usable, wherein aggregating the heart rate samples comprises determining a value that is representative of the heart rate samples; and
if the aggregated heart rate samples are smaller than the current minimum heart rate result, blending the aggregated heart rate samples into the current minimum heart rate result.
- 8. A computer system for determining a minimum heart rate, comprising:
one or more processors; and memory comprising instructions that are executable by the one or more processors to:
initialize a current minimum heart rate result; and
for each of a plurality of sampling periods when a wearer of a wearable device is asleep:
obtain via the wearable device a sequence of heart rate samples for the wearer;
assess whether a threshold percentage of the heart rate samples is usable; and
if at least the threshold percentage of the heart rate samples is assessed to be usable:
aggregate the heart rate samples assessed to be usable, wherein aggregating the heart rate samples comprises determining a value that is representative of the heart rate samples; and
if the aggregated heart rate samples are smaller than the current minimum heart rate result, blend the aggregated heart rate samples into the current minimum heart rate result.
- 15. A computer-readable medium having computer-executable instructions stored thereon that, when executed, cause one or more processors to:
initialize a current minimum heart rate result; and for each of a plurality of sampling periods when a wearer of a wearable device is asleep:
obtain via the wearable device a sequence of heart rate samples for the wearer;
assess whether a threshold percentage of the heart rate samples is usable; and
if at least the threshold percentage of the heart rate samples is assessed to be usable:
aggregate the heart rate samples assessed to be usable, wherein aggregating the heart rate samples comprises determining a value that is representative of the heart rate samples; and
if the aggregated heart rate samples are smaller than the current minimum heart rate result, blend the aggregated heart rate samples into the current minimum heart rate result.
