Heart rate variability characterizes the functional state of internal organs and body systems
Oriental specialists study a pulse wave at 6 points: three on the left wrist and three on the right. This is requires many years of study and experience to be able to characterize the pulse wave and diagnose a functional state of internal organs and body systems.
A modern computerized instrument "VedaPulse" allows doing it with great accuracy.
How does it works?
"VedaPulse" measure the change in the rhythm of the heart every millisecond. The duration of each heart cycle differs from the previous one and is estimated by the device.
The network of blood vessels covers the entire body. The movement of blood begins from the ventricles of the heart, then along the arteries and capillaries reaches the most remote parts of the body and returns to the atria through the veins. The branched circulatory system has to constantly respond to various changing needs of the body. For example, in order to perform any physical work, a flow of blood rushes to the muscle; while digesting food, the flow of blood rushes to the stomach. Inflamed tissue requires increased flow of blood.
It looks like heart listens to the internal organs and to their needs. A change in the pulse wave is a consequence of the changing rhythm of the heart.
However, in order to provide blood to all organs, the nervous system collects information about the needs and regulates the work of the heart and blood vessels.
Autonomic Nervous System (ANS) is tied to every automatic process in the body and comprises of two main branches that control the body’s stress and recovery processes. It regulates blood sugar, body temperature, blood pressure, sweat, digestion, and much more. With VedaPulse ANS can be precisely measured.
The autonomic nervous system has two divisions: the sympatheticc nervous system (SNS) and the parasympathetic nervous system (PNS).
Heart rate is primarily controlled by vagal, PNS activity. The parasympathetic nervous system controls the body at rest and is responsible for the body's "rest and digest" function.
The sympathetic nervous system (SNS) controls the body's responses to a triggers and is responsible for the "fight or flight" response. Sympathetic and parasympathetic divisions function antagonistically to preserve a dynamic modulation of vital functions. The SNS tightly connects with adrenal glands and regulates release of the adrenal hormones (epinephrine and norepinephrine). It accelerate the heart rate. ... The reduced heart rate results from an increase in activity of the PNS a decrease in activity of the sympathetic nervous system. The SNS is faster system. PNS is slower system. PNS uses acetylcholine (ACh) as its neurotransmitter. Each system dominates at a particular time which affects the body accordingly.
The autonomic nervous system is highly adaptable and allows the organism to maintain its balance when experiencing strain or stress. Conversely, a lack of flexibility and a rigid system can lead to somatic and psychological pathologies increased risk for adverse cardiovascular events, including ventricular arrhythmias and sudden death.
Spectral components of heart rate frequencies
The heart is the most powerful source of electromagnetic energy in the human body, producing the largest rhythmic electromagnetic field of any of the body’s organs. The heart’s electrical field is about 60 times greater in amplitude than the electrical activity generated by the brain.
Various regulation systems of the heart modulates various frequencies of the pulse wave that can be recorded with VedaPulse
There are three main spectral components: HF – high frequency, LF- low frequency, VLF – very low frequency. HF - respiratory waves, or fast waves (T = 2.5-6.6 seconds, v = 0.15-0.4 Hz), reflect respiration processes and other types of PNS activity, on the spectrogram are marked in green; LF - the average waves (T = 10-30 seconds, v = 0.04-0.15 Hz), are associated with SNS activity, on the spectrogram are marked in red; VLF– very slow waves (T> 30 sec, v <0.04 Hz), reflection of CNS, and hormonal regulation, on the spectrogram are marked in blue;
VedaPulse is able to measure body regulatory level of SNS, PNS and CNS by pulse rate.
HRV is shows how the central nervous system regulates the autonomic nervous system, and of how peripheral neurons feed information back to the central level.
The Autonomic Assessment Report, developed by the HeartMath Research Center, provides physicians, researchers and mental health-care professionals with a diagnostic tool to detect abnormalities and imbalances in the autonomic nervous system and predict those at increased risk of developing various pathologies often before symptoms become manifest.
Heart intelligence is the flow of higher awareness and the intuition we experience when the mind and emotions are brought into synchronistic alignment with the energetic heart. When we are heart-centered and coherent, we have a tighter coupling and closer alignment with our deeper source of intuitive intelligence. We are able to more intelligently self-regulate our thoughts and emotions and over time this lifts consciousness and establishes a new internal physiological and psychological baseline [McCraty R, M Atkinson and R.T.Bradley, 2004].
