Features description for [EMPATICA_HEARTRATE][PROVIDERS][DBDP]:

Feature Units Description
maxhr beats The maximum heart rate during a time segment.
minhr beats The minimum heart rate during a time segment.
avghr beats The average heart rate during a time segment.
medianhr beats The median of heart rate during a time segment.
modehr beats The mode of heart rate during a time segment.
stdhr beats The standard deviation of heart rate during a time segment.
diffmaxmodehr beats The difference between the maximum and mode heart rate during a time segment.
diffminmodehr beats The difference between the mode and minimum heart rate during a time segment.
entropyhr nats Shannons entropy measurement based on heart rate during a time segment.

!!! note "Assumptions/Observations" We extract the previous features based on the average heart rate values computed in 10-second windows.
