We tested the accuracy of the BG2 RRI extraction against standard clinical ECG derived RRI during rest and different types of physical activity (walking,
running, biking) in 19 healthy volunteers. BG2 detected on
average 99.95% of the heartbeats (0.05% of beats missed) and had
0.16% extra beat detection rate, with 2.96ms (0.54%) mean
absolute error (MAE) in RRI as compared to the standard ECG.
When Firstbeat artifact correction was applied to the data,
erroneous detections were further reduced (0.04% extra
detections, 0.02% missed beats). BG2 provides accurate data for
HRV analysis.
