Zusammenfassung:A wearable device for determining a photoplethysmogram, includes at least a first light source arranged to provide light towards at least one entry point on a proband's body when the wearable device is used by the proband. The wearable device further includes at least first light detector arranged to detect light received from the light source through the proband's body. The wearable device further includes a control means arranged to calculate a photoplethysmogram based on the detected light. The wearable device further includes at least a first and a second detector optical waveguide arranged to detect light in at least two different positions on the proband's body when the wearable device is used by the proband and feed it to the at least first light detector.
