Description
Technical field
This utility model relates to a kind of Physiological Analysis instrument, specifically, relates to a kind of heart rate variability (Heart Rate Variability, HRV) measuring instrument.
Background technology
In current society, the fast pace of life and violent competition make people be in highly compressed stress state for a long time, and this state all exerts a certain influence for people's physiology and mental health.From physiology, secular pressure state makes people's immunity degradation, is easy to ill; Psychologically, pressure easily causes people to produce emotional problems such as depression, anxiety.Recent years, people begin to take different means to prevent physiological decease and promote mental health, as the intelligence awareness training in the psychology, the Yoga in the physical training or the like.
(Heart Rate Variability HRV) is meant the speed diversity of heart rate to heart rate variability, and the health that to be prediction caused by pressure is the efficiency index of overdraw excessively.Health excessively overdraw can cause health to make suitable function self regulation to external and intrinsic pressure, is easy to produce physiology and mental illness.HRV is meant the sinus rate phenomenon of periodically-varied within a certain period of time, is reflection sympathetic nerve and parasympathetic nervous (vagus nerve) tension force and equilibrated important indicator thereof.The variation of HRV has reflected the autonomic nerve adjustment state of sinuatrial node level.Normal person's heart rate is a sinus rhythm, and sinuatrial node is the leading pacemaker of heart, the active receiving sympathetic nerve of sinuatrial node and parasympathetic duplicate innervation.So, the stable accurate balance that depends between sympathetic nerve-parasympathetic nervous of normal person's electrocardio.
Sympathetic nerve and parasympathetic nervous system have been formed autonomic nervous system, and the two is under cerebral cortex and hypothalamic domination, mutually antagonism, coordinate mutually and carry out active.The internal organs of the overwhelming majority all have been subjected to sympathetic and parasympathetic double innervation.Parasympathetic major function is to keep the normal activity of body interior, and sympathetic nerve be mobilize body interior stress be movable.To active dominations of internal organs such as the digestion of body, breathing, circulations, and the function of regulating internal organs and body of gland guarantees the balance of body internal and external environment by sympathetic and parasympathetic nervous system.
By the research to cerebral nervous system, people find also that at heart rate variability sympathetic parasympathetic nervous activates situation, hypothalamus activates between situation, the hormonal system variation and exists certain synchronous variation relation.Therefore, by monitoring and adjusting HRV, we can regulate autonomic nerve and hormonal system etc. simultaneously.
In addition, psychologist finds that also autonomic nerve has important function to being emotionally stable of people.In recent years, people began to treat from the control principle of living organism internal balance the production process of emotion.Psychologist thinks that emotion is a baseline with organic a kind of organized stability, and this stability is organic normal processes and the suitable state of regulating by autonomic nervous system.
So, improve HRV, promote the autonomic nerve balance can allow people adapt to the pressure that produces by physiology and emotion better; Can improve such as headache, anxious syndrome, confirmed fatigue, Sensitive disease, acute and chronic dysfunction, anxiety disorder and depression or the like.
At present, HRV can measure by time domain or frequency domain index.The electrocardiographic recorder that adopts generally has the branch of short distance 5min and long-range 24h.Time domain measurement is based on the time length in the signa, aspect heartbeat interval or the difference between interval of normally beating.Technical, the interval of beating, be meant that " R " arrives the time in the signa between " R " ripple on the electrocardiogram.HRV time-domain analysis method is simpler, and the index meaning is directly perceived, and the evaluation total to HRV is provided, but is difficult to reflect sympathetic nerve and parasympathetic balance.
The frequency domain measurement method of HRV is the information that the frequency distribution aspect of HRV composition is provided by the power spectral-density analysis method.Index high frequency (HF) composition (0.15-0.40Hz) that the HRV Spectral Analysis Method is commonly used is measured vagus nerve to regulating the influence of sinuatrial node; Low frequency (LF) composition (0.04-0.15Hz) is influenced by sympathetic nerve and parasympathetic nervous jointly; And intrasonic (VLF) composition (0.003-0.04Hz), react of the influence of several factors to heart, comprise chemoreceptor, temperature receptor, renin-angiotensin system and some other unconventional factor.
HRV is carried out the short distance spectrum analysis, and the scope of these three kinds of compositions all is included in nearly all variation.Total frequency spectrum (TF) is the total variability of signal, represents the summation of HF, LF, VLF.LF/HF represents the poised state of sympathetic-vagal tone.Frequency domain analysis more can be analyzed sympathetic nerve and parasympathetic function status effectively particularly.
HRV is used for studying non-angiopathys such as rhythm of the heart as fetus, thyroid disease, diabetes, sacred disease, senescent deterioration more, comprises the definite of monitoring, prognosis judgement and diabetes nerve infringement that state behind sudden death, the myocardial infarction, heart failure, heart transplantation are repelled but more research is heart physiological, cardiovascular drugs, heart disease.
In recent years, people carried out power spectrumanalysis to 24 hours retrospective information of electrocardiosignal of ambulatory electrocardiogram (Holter) record.But because Holter needs monitoring in 24 hours, the HRV test instrunment that uses is 24 hours methods of testing mostly at present, instant electrocardio is changed and can not in time reflect, after need waiting until that detection in 24 hours finishes, just can recognize ecg information in observation process by playback, use very not conveniently, can not satisfy the popular requirement that needs to grasp changes in heart rate.
Also have researcher to design journey (the shortest 15 minutes) electrocardiosignal gauge in short-term, but it is used to medical field.The instrument of at present relevant HRV all belongs to electronic medical instruments; as be used for the HRV of the sick sudden death of diagnosis of diabetic autonomic neuropathy, analysis of cardiac high-risk patient, not specially at portable, the HRV equipment and the supporting biofeedback training fast of ordinary people's design.
