Heart Rate Variability (HRV) For Autonomic Nerve System Evaluation
The Heart Rate Variability (HRV) test is an established, non-invasive electrophysiology test for an assessment of the cardiac autonomic nervous system.
Heart rate is not fixed. In healthy individuals, heart rate varies constantly as a means to adapt to internal and external stress. Heart rate automatically adjusts for stress from emotional conflict, heavy metal toxicity, hidden dental distress, allergies, respiration, metabolic changes, thermoregulation, physical exertions and long-term diurnal and endocrine cycles.
The modulation of heart rate is primarily the result of alterations of the autonomic nervous system as represented by the parasympathetic system (for your ability to relax, repair, digest, eliminate and sleep) and the sympathetic system (for fight or flight).
Minor heart rate variation can be measured by computer and categorized for sympathetic and parasympathetic dominance.
HRV testing, in addition to a routine cardiac stress test, is a valuable screening tool for people over 40 years old. It provides a quick measurement for one’s general fitness and cardiac risk factors. The HRV test can also play an important part in assessing the role of the autonomic nervous system in diverse conditions such as dizziness, cardiac arrhythmias, heart failure, sleep disorders, hypertension, and obesity.
HRV testing is also used to monitor the therapeutic effects of chiropractic and cranial therapy, massage and exercise and a wide range of integrative treatments including supplements and medications.
HRV is an important asset in an assessment of one’s total body condition when combined with other complementary medical evaluation techniques.
