HRV - 應用

Application of HRV in the field of health management


In Physiology, heart rate variability is a cardiovascular contraction and expansion of neural activities in the brain arising out of fluctuations in General, which is under the influence of various physiological a constant factor. Due to these factors the length between successive heartbeats, also referred to as heart rate or RR interval, and we use this data to do a mathematical calculation and heart rate variability. When you increase or decrease heart rate variability will be reflected in two ways: among the different heart rate ( based on the time to express, MS) and the spectrum of different power ( expressed based on frequency, Hz).

Current variation of heart rate analysis are commonly used in the clinical lead rates below include:


(1) Heart and cardiovascular disease

Attenuation of the vagus nerve are considered associated with acute myocardial infarction ( Heart rate variability can be a pointer to the prognosis after myocardial infarction ) 。 Heart rate variability and cardiac complications in custody, as well as the risk of cardiac arrhythmia are highly relevant. Attenuation of the vagus nerve is found in coronary artery disease patients with essential hypertension. HRV spectral power attenuation, can serve as a heart transplant, prediction pointers for exclusion.


(2) neuroscience

Can reflect a patient's heart rate variability of Central autonomic nervous system disorders, such as Parkinson's disease, spinal deterioration, cerebellar Shy-Drager Syndrome, multiple sclerosis, chronic alcoholism, Guillain-Barre Syndrome, limb paralysis, and so on.


(3) diabetic

Diabetes caused by myocardial disease would reduce heart rate variability. Reduced heart rate variability and often before the clinical symptoms, heart rate variability as a pointer for early warning of diabetes, especially in children.


(4) renal insufficiency Glomerular nephritis

Vagus nerve attenuation is reflected in heart rate variability of patients with uremia on power reduction in the SW region of the spectrum.


(5) the pharmacological effects of

Calcium blockers (atenolol) And the beta blockers (diltiazem) , Mental stability agents, tranquilizer, scopolamine(vagomimetic) Increases vagus nerve activity. Conversely, atropine (atropine) can reduce the activity of the vagus nerve. It is interesting,nifedipine ( a calcium Blocker ) but will not have any effect on heart rate variability.


(6) Toxicology

Analysis of heart rate variability can display a variety of toxic chemicals in the environment causing severe autonomic nervous system disorders, such as organic solvents, pesticides, nitrates, organic phosphorus, lead, etc.


(7) the working pressure

Adverse vibration tool operation, operational systems, all kinds of dust, does not meet the ergonomic way of working, overwork, poor working atmosphere would reduce heart rate variability. Heart rate variability can be used for quantitative assessment and control for these factors.


(8) Medical Ecology

Source of ecological risk assessment, should not only stop at the eco-evaluation of levels of toxic substances, further observation, pollution of biological communities in the region, of danger on their common impact of functional status. These can, through the analysis of heart rate variability, sympathetic tension observed long-term increase.


(9) sports

Effect of overtraining, easing steps and their use of drugs, are available through to successful control of heart rate variability.


(10) in applied psychology

Applied multiple regression analysis can be found on the steps, frustration, fatigue, lack of social support, locus of control mechanism of instability, poor family and social connections, will increase heart rate variability power while reducing the overall power of the long wavelength region of the spectrum.


(11) non-traditional medical treatment

Free medical care, medicine, aromatherapy, massage, steam bath, autogenous training, yoga, Silva Method Difficult to assess the effectiveness of the method, unless you are using heart rate variability to look at the comprehensive functionality of their State.


(12) Transport, military and space medicine

These specialized professional or special events, advance reserves say they have a high level of health and adaptation ability. And in these cases for the physical and mental requirements, through a reliable assessment of heart rate variability.


(13) health insurance

Recently in Norway and Japan have some of application of heart rate variability as a pointer to a forecast overall health risk. Heart rate variability (HRV) analysis to predict a new disease of civilization and burnout.
