Don't miss a beat: How algorithms can be used in medtech

Arrow Electronics in conjunction with Analog Devices' comprehensive portfolio of technology and design solutions are helping shape the future of healthcare equipment and device designs. Our true systems approach to functional integrations allows us to collaborate with customers, creating a differentiation in the marketplace.

Heart rate variability (HRV) from electrocardiograms (ECG) is a well-known diagnostic method for the assessment of autonomic nervous function of the heart. A more convenient approach to assess cardiac function is by using photoplethysmography (PPG) waveforms where pulse rate variability (PRV) replaces HRV. However, the unavailability of robust detection algorithms for PPG signals has prevented the medical market from providing clinical diagnosis using PRV and from measuring biological information for wellness purposes, such as sleep stage, stress state, and fatigue.

This article provides a robust peak and onset detection algorithm for beat-to-beat pulse interval analysis using PPG signals. We demonstrate our method through large data collection with the Analog Devices, Inc. (ADI) multisensory watch platform with high coverage, sensitivity, and low root mean square of successive difference (RMSSD) as compared to the beat-to-beat results from ECG signals.
