Heart rate variability (HRV) provides indirect insight into autonomic nervous system tone, and has a well-established role as a marker of cardiovascular risk. The SDANN is similar, but requires that you first take the average RR interval from several 5 minute sections of a recording, and then the standard deviation. When your system is in fight-or-flight mode, the variation or difference between heartbeats is minimal, and when it is relaxed, the variation is significant.

When your heart is beating normally but the variability between heartbeats is greater than 0.12 seconds, this is called sinus arrhythmia. Heart rate variability can sometimes meet the criteria for sinus arrhythmia. One of the first things to know when understanding heart rate is that the most informative metric relies not just on the heart rate, but how much the heart rate varies. Your heart rate variability also tends to decrease normally as you get older. Figure 3.1 Heart rate variability is a measure of the normally occurring beat-to-beat changes in heart rate. It is of course an understatement to say that the heart is critical for our well-being. Longer monitoring times tend to give the best data. Outside of a medical setting, there are several devices commonly used by athletes, especially runners. The extent to which the heart rate changes within a set amount of time, or the extent to which it is spread over different frequencies, will determine the amount of HRV. Our ANS responds to negative stimuli such as stress, poor sleep, and unhealthy diets, but also to positive stimuli such as good news, seeing a loved one, or having a nourishing meal.
