Description

<p>The aim of this study is to compare the heart rate (HR) derived from electrocardiogram (ECG) with the pulse rate (PR) derived from the green light ear photo-plethysmogram (PPG) using an earphone. The PPG sensor comprising a green LED and phototransistor was embedded into an earphone. In 10 subjects, simultaneous measurements of ECG, and green light (525 nm) PPG from the front of tragus were made at the following treadmill speeds: 0, 2, 4 km/h. During walking (2, 4 km/h), the results showed that the PR derived from the green light PPG from the ear significantly related to HR derived from ECG (r = 0.98). In addition, the limit of agreement in Bland-Altman plots between these indices were ± 3.95 (1.96 SD) bpm. In conclusion, these findings suggest that the green light ear PPG using earphone might be practical measurement for monitoring HR during walking. </p>
