We compared the pulse rate (PR) derived from the ear photoplethysmogram (PPG) using a green light with the heart rate (HR) derived from the electrocardiogram (ECG) as a reference. In 20 young healthy participants (21.7 ± 2.7 S.D. years), simultaneous measurements of the ECG (chest lead II), peak green light (525 nm) PPG, and peak near-infrared light (810 nm) PPG from the two sites of the ear (tragus and helix-crus) and index fingertip, respectively, were made. We used a treadmill for walking task, at speeds of 0, 2, 4 and 6 km/h. The results showed that the PR derived from the green light PPG from the ear significantly related to HR derived from ECG (tragus: r = 0.984, helix-crus: r = 0.972, respectively). In addition, the limit of agreement (± 1.96 S.D.) in Bland-Altman plots between PR and HR were ± 5.960 bpm and ± 7.944 bpm. In conclusion, these findings suggest that green light ear PPG could be the basis of a suitable, practical, method for monitoring PR in normal daily life.
