HRV

What is HRV and why should I care?

Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats.

It is measured by the variation in the beat-to-beat interval. HRV is interesting because it was discovered that there is a high correlation between a high rate of variability and change between heart beats to feelings of emotional stress.
