Does a microcontroller-based real-time HRV measurement system accurately measure HRV parameters compared to actual heart rates?
Effect estimate: r > 0.99
A newly developed microcontroller-based real-time HRV measurement system using a low-complexity R-peak detection algorithm provides highly accurate and reliable HRV parameters.
Wei et al. (2013) studied this question. Microcontroller-based real-time HRV measurement system vs. Actual heart rates was evaluated on Heartbeat error rate and correlation with actual heart rates (r > 0.99). A microcontroller-based real-time HRV measurement system demonstrated a heartbeat error rate of less than 1 bpm and a high correlation (r > 0.99) with actual heart rates.
