O
Outcome
Validity and reliability of short-term resting heart-rate variability (HRV) measures (SDNN, RMSSD, LF, HF, LF/HF ratio, mean RR)surrogate
The Polar S810 heart-rate monitor provides valid short-term resting HRV measures compared to a 12-lead ECG, though measures are inherently unreliable over a 1-week interval.
Limitations
- Reliability of HRV from longer (e.g., 10 min) and/or consecutive 5-min RR recordings needs to be investigated
