An average HRV score was generated for each person that fulfilled this criteria and those average scores were used to develop statistical HRV results. Frequency Domain Analysis is a complex analysis technique that shows how much of a signal lies within one or more frequency bands (ranges). While heart rate variability may be present in healthy individuals, it can still indicate the presence of health problems, including heart conditions and mental health issues like anxiety and depression. Heart rate variability (HRV) consists of changes in the time intervals between consecutive heartbeats, called interbeat intervals (IBIs). This evidence supports the concept that overall, sleep is a condition during which vagal activity is dominant.
