Does a wristband PPG device accurately estimate heart rate compared to ECG during various activity conditions?
A wristband PPG device accurately estimates heart rate during sedentary tasks, but its accuracy significantly decreases during physical activities like walking and jogging.
PPG wristbands may suffice for sedentary HR monitoring; leaves open reliability during activity pending larger validation.
Accurate monitoring of heart rate (HR) during various activities is crucial for assessing cardiovascular health and optimizing performance. In this study, we evaluated the accuracy of a wristband PPG device for estimating HR across different activity conditions. Seventeen subjects participated, each equipped with a wristband PPG device and an ECG as a reference, while performing office tasks, walking, jogging, and running. We compared the estimated HR provided by the PPG device to the HR estimated from the synchronously recorded ECG, calculating the relative errors (Eᵣ) for each activity phase. During office tasks, 100% of the recordings exhibited Eᵣ below 10% and 5%. However, during walking, this percentage decreased to 69% and 63%, and further dropped to 50% and 3 8 % for jogging, respectively. In this work the HR provided by the wristband PPG device was validated. However, given that the device provides the raw PPG and accelerometer signals, further development of signal processing algorithms may improve HR estimation.

Barquero et al. (2024) reported a cross-sectional. Wristband PPG device vs. ECG was evaluated on Relative error of estimated HR compared to ECG across activity phases. A wristband PPG device accurately estimated heart rate during office tasks (100% of recordings with <10% relative error), but accuracy decreased during walking (69%) and jogging (50%) compared to ECG.
