Key result
The Polar S810 monitor showed excellent agreement with conventional ECG for time-domain heart interval variability, with functionally irrelevant differences (e.g., mean R-Ri difference of -1.85 ms).
Why the study?
Does the Polar S810 wrist-worn heart rate monitor provide reliable time-domain heart interval variability indices compared to conventional ECG in adults?
Cross-Sectional (n=33)
Does the Polar S810 wrist-worn heart rate monitor provide reliable time-domain heart interval variability indices compared to conventional ECG in adults?
The Polar S810 wrist-worn heart rate monitor is a feasible and reliable alternative to conventional ECG for recording short-term heart rate variability.

Supports Polar S810 for short-term HRV assessment; leaves open validation in clinical populations.
Porto et al. (2008) conducted a cross-sectional in normal or with different clinical conditions (n=33). Polar S810 monitor vs. conventional electrocardiogram (ECG) was evaluated on Agreement between time-domain variability indices of 5-minute R-Ri. The Polar S810 monitor showed excellent agreement with conventional ECG for time-domain heart interval variability, with functionally irrelevant differences (e.g., mean R-Ri difference of -1.85 ms).
