What is the Heart Rate Variability (HRV)?<\/h1>\n
The implementation of the body\u00b4s own vibration into music is based on the principles of the analysis of the Heart Rate Variability (HRV) analysis. Heart rate variability, an established scientific analysis method, has been in use for many years already. This variability of the heart rate is regulated by the rhythmic changing activity of the parasympathetic and sympathetic parts of the autonomic nervous system (ANS). Today HRV is regarded as a global indicator of the regulatory capacity of a human being.<\/p>\n
In contrast to the general assumption, a healthy human heart does not beat at exact, regular intervals in relation to the distance between each heartbeat, but subtly irregularly (RR1,RR2…. see chart).![\"\"](\"https:\/\/www.aquaquinta.com\/wp-content\/uploads\/2018\/05\/RR-intervals-700px.jpg\")
<\/p>\n
The distance between two heartbeats is defined as the time interval between the beginning of two contractions of the heart chambers. This beginning of the contraction appears in the Electrocardiogram (ECG) as the so-called R-Point (upward “R” spikes of the graphical deflections seen on a typical ECG wave). The distance between the R-points is called RR-Interval or IBI (Interbeat Interval).<\/p>\n
Essentially the HRV is based on the functional interaction of the sympathetic- parasympathetic system and the sinoatrial (sinus) node, which can only partly be influenced intentionally. It is called the sympathovagal modulation of the sinus node activity.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
The Heart Rate Variability test is an established, non-invasive electrophysiological test for an assessment of the cardiac autonomic nervous system.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
There are variations with every beat of the heart. This makes sense because the organism, and thus also the heart, is constantly influenced by external and internal stimuli. A stress situation for example, caused by physical and \/ or mental stress, leads to an adaptive response of the heart, showing a decrease in the variation range of the heart rate. On the other hand, the variation range increases during rest and relaxation.<\/p>\n
Parasympathetic nervous system<\/h3>\n
The parasympathetic nervous system is generally responsible for recovery actions, energy storage, digestion, sleep, and building processes of the body (trophotropic actions – relating to the innate inclination for preservation and restoration of depleted nutritional supplies). It decreases the blood pressure and decelerates the heart beat (bradycardia).<\/p>\n
The main player of the parasympathetic nervous system is the Vagus, the tenth cranial nerve (vagus – \u201cwandering\u201d nerve). It reaches from the cerebellum and brainstem to the lowest viscera of the abdomen, passing the heart and major organs on its way through the body. Respiration has a big effect on the activity of the vagus. During inhalation its activity declines and during exhalation the vagus can unfold itself.<\/p>\n<\/div>\n<\/div>\n
\u201cLearn how to exhale, the inhale will take care of itself.\u201d<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n The main function of the sympathetic nervous system is to control active processes in the body. It is often referred as the \u201cfight or flight\u201d response of the body. It is responsible for the energy provision and discharge, degradation of metabolic processes (ergotropic mechanisms \u2013 the functional status of the nervous system that favours the organism’s capacity to expend energy), respiration, the acceleration of the heart beat (tachycardia) and increase of blood pressure. The sympathetic activity increases the preparedness for action. It increases the blood glucose levels to guarantee a fast energy source, and increases one’s level of attention and the power of concentration.<\/p>\n<\/div>\n<\/div>\n<\/div>\n The Autonomic Nervous System controls the involuntary actions of the smooth muscles, heart, glands, stomach, bladder and blood vessels. The purpose of the ANS is also to regulate and balance tension and relaxation in the body. This is achieved through the antagonistic interaction of the sympathetic and parasympathetic nervous system.<\/p>\n<\/div>\n<\/div>\n<\/div>\n The sympathetic- parasympathetic system is influenced through the central mechanisms (brain) as well as the feedback from the periphery (organs). Thereby the measurements of the HRV can make a statment of the central mechanisms (brain) as well as of the organs.<\/p>\n In a nutshell it means that the higher the HRV the faster the heart can adjust to internal or external influences, and the better the organism reacts to the environment. A low HRV could be an indicator of limited health conditions, therefor acute risks in the \u00a0cardiovascular system, physical illness, cancer or neuropathies.<\/p>\n The HRV could be compared with an indication of fever: Different kinds of diseases can be shown by fever or in a reduction of \u00a0the HRV, although a lot of different causes may be the trigger for both\u00a0parameters .<\/p>\n Since time immemorial humans focused on the pulse, its relation to the self- healing ability of the body and how it can be used to diagnose different causes. One of the most famous and probably most quoted person in relation to HRV is the physician Wang Shuhe, who lived 1700 years ago in China.<\/p>\n The sentence \u201eIf the heartbeat gets as regular as the knocking of theSympathetic nervous system<\/h3>\n

History of HRV<\/h3>\n
\nwoodpecker or the dripping of the rain on the roof the patient will die within 4 days\u201c describes beautifully the knowledge and awareness, which must already have existed at that time in relation to the variability of the heartbeat. His book \u201cMai Ching\u201d in which he divides the pulse into 24 different types, had a big influence on Chinese Medicine.
\nUp to today the analysis of the puls is an important method in traditional Chinese Medicine to get an understanding of the actual state of a patient.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/section>
