Accuracy of heart rate variability estimated with reflective wrist-PPG in elderly vascular patients

Abstract Optical heart rate monitoring (OHR) with reflective wrist photoplethysmography is a technique mainly used in the wellness application domain for monitoring heart rate levels during exercise. In the absence of motion, OHR technique is also able to estimate individual beat-to-beat intervals r...
