RRi

The RRi values are sent as part of the final results.

The application can receive the RRi result by implementing VitalSignsListener:

Dart

@override
void onFinalResults(VitalSignsResults results) {
    VitalSign? vitalSign = results.getResult(VitalSignTypes.rri);
    if (vitalSign is VitalSignRri) {
        for (var rriValue in vitalSign.value) {
          print("RRI value: $rriValue");
        }

        print("Confidence Level: ${vitalSign.confidence?.level.toString() ?? "N/A"}");
    }
}

For general information about vital signs see the Vital Signs and Health Indicators Information Document.

For a list of supported vital signs by platform and measurement mode (face/polar), along with their required measurement durations, refer to the Indicators Technical Information page.
