Method
- A beat is an artifact when its RR interval is outside 300–2000 ms, differs by more than 20 % from the median of the 11 beats around it, or was marked by the sensor.
- Artifacts are excluded from every statistic. RMSSD uses only pairs of consecutive clean beats.
- SD1 and SD2 are the spreads of the Poincaré plot across and along the identity line: short-term and long-term variability.
- Heart rate by phase is 60000 / RR of clean beats, not the value reported by the sensor.
