SDNN
Based on 2 sessionsOverall spread of the intervals between beats over the minute recorded.
On average, the change is 38.5 ms
RMSSD
Based on 2 sessionsSpread between consecutive beats. Sensitive to parasympathetic (calming) activity.
On average, the change is 31.5 ms
LF/HF
Based on 1 sessionsRatio of slow to fast oscillations in the rhythm. There is no generally accepted interpretation of this metric.

Variability is measured twice during the viewing: in the first and the last minute. A metric is considered unchanged when the shift is below 5% of the first measurement.
Only completed sessions with a reliable measurement are counted. Percentages and averages are computed over each participant's first session. Pulse is considered unchanged when the shift is below 3 bpm.
