Abstract

A photoplethysmography or PPG signal processing device, comprising a processor and memory including computer program code, configured to cause the PPG signal processing device to:- obtain (101) at least one PPG signal (200) for a human or animal;- detect (102) heartbeats (201, 202, 203, 204, 205, ...) in the at least one PPG signal (200);- determine (103) interbeat intervals (301, 302, 303, 304, ...) for pairs of consecutive heartbeats (201-202, 202-203, 203-204, 204-205, ...) in the at least one PPG signal (200);- detect (104) interbeat interval baselines, each interbeat interval baseline (302-304) corresponding to a plurality of consecutive interbeat intervals (302, 303, 304) that are constant within a variability tolerance;- determine (105) respective central interbeat interval values (401, 402, ...) for the interbeat interval baselines (302-304); and- detect (110) a relationship between the central interbeat interval values (401, 402, ...; 501, 502, ...).
