Evaluation of robust HRV analysis against motion artifacts for wrist-worn PPG device

View Publication

Abstract

Heart rate variability (HRV) analysis in wristband PPG device is gathering interest for emotion related and well-being application; however, motion artifact is critical issue. We verified robust framework against motion artifacts for detecting HRV by motion-tolerant instant heart rate (IHR) detection algorithm. The results suggested high correlation between HRV calculated from PPG by our method and HRV calculated from ECG, and the improvement in stress/resting classification in PPG even when motion artifact occurred.
