System, method and computer program for monitoring health of a person

A system for monitoring health of a person during a health monitoring session (s), wherein the system comprises:

• a heart rate sensor arranged to measure heart beats of the person for providing heart rate measurement data, and
• a data processing system configured to:
• receive (A) the heart rate measurement data from the heart rate sensor during the health monitoring session (s), and
• analyse (C) the heart rate measurement data such that in the analysis, the data processing system is configured to:
• calculate (C1) instantaneous heart rate data comprising heart rate of each measured heartbeat, the calculating being performed over a time window (w) in the health monitoring session (s), the time window (w) comprising a timepoint (t), the instantaneous heart rate data being calculated based on the heart rate measurement data received from the heart rate sensor,
• provide (C2) a periodic biofeedback function comprising parameters and a cumulative difference (E) relative to the instantaneous heart rate data, the parameters comprising:
• an amplitude (A) determining a heart rate variability of the person at the timepoint (t), and
• an angular frequency (P) of the periodic biofeedback function at the timepoint (t),
• fit (C3) the periodic biofeedback function into the instantaneous heart rate data within the time window (w) to determine:
• the parameters of the periodic biofeedback function at the timepoint (t), and
• the cumulative difference (E) at the timepoint (t).

A method for monitoring health of a person during a health monitoring session (s), wherein the method comprises:

• measuring heart beats of the person for providing heart rate measurement data with a heart rate sensor,
• receiving the heart rate measurement data from the heart rate sensor into a data processing system,
• analysing the heart rate measurement data in the data processing system by:
