Heart Rate Variability

What is Heart Rate Variability (HRV)?

HRV is the inter-beat variability between successive heart contractions, or the change in time between successive heart beats. Variability in heart rate is a result of the adaptive and regulatory processes within the body and is a good thing.rr_interval.png

HRV is an accurate, non-invasive measure of the Autonomic Nervous System and therefore health.


The Impact of HRV On Your Health

Changes in HRV have been correlated to the top 6 leading causes of death in Australia, including:

  • Coronary heart disease
  • Dementia and Alzheimer's disease
  • Cerebrovascular disease (stroke)
  • Cancer
  • Chronic obstructive pulmonary disease
  • Diabetes

HRV is also linked to many of the risk factors associated with these diseases such as hypertension, obesity, glucose intolerance, insulin sensitivity, stress, etc.

When monitored regularly, HRV can also be used for prediction or early identification of an acute sickness or a medical issue.




HRV Biofeedback

HRV biofeedback is the process of measuring live HRV and using the “feedback” information in conjunction with changes in thinking, emotions, and behavior to support desired physiological changes. The goal of HRV biofeedback is to enable an individual to learn how to influence their HRV for improved health and wellbeing.
