ASSESSMENT OF INDICATORS OF TEMPORAL ANALYSIS OF PSNS

All indicators of the temporal analysis are intended primarily for evaluating the function



SDNN indicators (ms) - standard deviation (?) And RRNN (ms) - Xav (s) are described in statistical indicators.

The rMSSD (ms) is essentially calculated and interpreted in the same way as the SDNN (ms).

NN50count and PNN50 (%) reflect the number of changes in the duration of neighboring ICs for more than 50 ms. The value of the PNN50 indicator (%) does not depend on the recording time and in healthy people it always exceeds 10-15%.

In evaluating short-term records, rMSSD (ms) is preferable to indicators

pNN50 (%) and NN50count, as it has the best statistical properties.

ASSESSMENT OF INDICATORS OF TEMPORAL ANALYSIS OF PSNS

  1. ASSESSMENT OF INDICATORS OF SPECTRAL ANALYSIS
    All indicators are subject to assessment, but the most important are: TP (ms2), HF (%), LF (%), VLF (%), LF / HF and IC. The values ​​of all parameters of the spectral analysis can vary greatly with poor-quality preparation of the patient for the study, as well as in the presence of rhythm and conduction disturbances or artifacts in the analyzed section. The indicator of the total spectrum power - TR (ms2) is
  2. ASSESSMENT OF INDICATORS OF AUTOCORRELATION ANALYSIS
    When conducting spectral analysis, autocorrelation indicators are usually not evaluated. The 1k exponent is usually less accurate than M0. The M0 index corresponds to the number of autocorrelation shifts through which the first negative value of the correlation coefficient appears. It has low values ​​with a good functional state of the CCC and increases when waves of low and very high prevail in the rhythmogram
  3. Analysis methods and indicators
    The characteristics of HRV can be determined using many different methods, each of which reflects one of the sides of the studied phenomenon. Typically, these groups of methods are distinguished: 1) the time domain (statistical and geometric); 2) the frequency domain; 3) autocorrelation analysis; 4) nonlinear; 5) independent components; 6) mathematical modeling. Temporary methods
  4. ASSESSMENT OF HISTogram DOME INDICATORS
    The histogram dome indicators are interpreted when it is impossible to reliably exclude episodes of rhythm and conduction disturbance or if there are recording artifacts. The higher the value of the indicators of the histogram dome, the higher the activity of the parasympathetic division of the ANS. For example, with close values ​​of indicators evaluating the maximum range of CI (? X, BP, W, etc.) in various patients
  5. EVALUATION OF VARIATION PULSOMETRY INDICATORS
    The most important indicators are AMo%, IN and BP (s). Fashion amplitude is one of the most important indicators of HRV. It is characterized by great resistance to artifacts and a fairly high sensitivity to changes in the functional state of the CVS. Normally, in healthy people under 25 years of age, the value of AMo% does not exceed 40%. During life, on average every 5 years, the value of the indicator increases by
  6. ASSESSMENT OF STATISTICAL INDICATORS
    The most important indicators are heart rate,?, Max (s), Min (s),? X, V (%). Typically, the heart rate ranges from 60 to 90 in 1 minute. With high-quality filtering of the record, the difference between Max (s) and Min (s) - the indicator? X corresponds to the amplitude of the natural oscillations of the rhythmogram and usually decreases with a deterioration in the functional state of the CCC. In the presence of at least one arrhythmic episode (for example,
  7. Analysis of expert information on quality indicators of dental care for the population
    In recent years, among managers of dentists, there has been a desire to strengthen the information, so-called signaling, value of statistical data and especially the final values ​​and indicators of the volume, quality and efficiency of work obtained from the reports of medical facilities of the dental profile. It seems to them a great value to rationalize the details of the information presented in them, rather than general
  8. EVALUATION OF ANTHROPOMETRIC INDICATORS AND PHYSICAL DEVELOPMENT OF A CHILD
    Methods by which physical development is studied include • anthropometry; • examination and description of the signs of physique and appearance (somatoscopy); • function research: dynamometry with the help of special dynamometer devices; • study of physical performance using a step test or bicycle ergometry; • physical indicators (vital lung capacity, ECG data,
  9. Psychotechnological methods of analysis, criteria and indicators of productive professional activity
    The development of psychotechnological methods for analyzing productive professional activities can go in two main directions, closely interacting with each other in the framework of a single psychotechnological project. These two areas of research are distinguished by those units that are methodologically accepted within their framework as the ultimate units of activity analysis. One of these
  10. ASSESSMENT OF INDICATORS OF CORRELATION RHYTHMOGRAPHY
    When screening, scatterogram values ​​are not evaluated. Typically, a scattergram is displayed in the range of 0.4 to 1.4 seconds. When you change the range visually, the dimensions of the scatterogram change. This circumstance is used when a detailed review of the elements of the graph is necessary. {foto161} {foto162} Scattergram of the patient in the range of 0.4-1.4 sec. That
  11. Clinical evaluation of HRV in various pathological conditions
    Organized and balanced regulation is the key to quality health, increases the patient's chances of recovery or remission. The response of regulatory systems to stimuli is nonspecific but highly sensitive, and accordingly the HRV analysis method is nonspecific, but highly sensitive in a variety of physiological and pathological conditions. However, you should not look for indicators and values ​​of HRV,
  12. CALCULATION AND ANALYSIS OF DEMOGRAPHIC INDICATORS: FERTILITY, NATURAL GROWTH.
    They can be calculated for the entire population, urban and rural. Below is the formula for calculating the coefficients for the whole year. Number of births N Total coefficient = __________________________________ * 1000 births Cr Average annual cash
  13. THEORETICAL SUBSTANTIATION OF APPROACHES TO THE EVALUATION OF INDICATORS OF PHYSICAL DEVELOPMENT OF CHILDREN AND ADOLESCENTS
    (Kuchma V.R., Skoblina N.A.) An analysis of the informativeness of methods for assessing indicators of the physical development of children and adolescents at the population and individual levels allows us to give preference to methods that use regional regression scales. Estimation by regional modified scales of regression of body weight by body length and a comprehensive scheme have much in common: - indicators of physical
  14. Informational content of methods for assessing indicators of the physical development of children and adolescents at the population level
    In the last decade of the XX and at the beginning of the XXI century, a number of works were published on the physical development of children and adolescents and its relationship with environmental factors and living conditions (Bogomolova ES, 1994, Mikhailova S.A., 1995, Sukhanova N. N., 1996, Svinarev M.Yu., 2002, Ivannikov A.I., Sitnikova V.P. et al., 2007, Belyakova N.A., 2006 and others). Using different assessment techniques
  15. Assessment based on labor analysis
    The determination of psychological properties based on an analysis of the work of managerial personnel takes place within the framework of a situational assessment, which, however, is similar to an assessment of traits. Only in this case, the relatively invariant features of the manager’s behavior appear as stable psychological characteristics, manifested in the process of solving specific managerial problems by him. In the technique
  16. Evaluation of a large system of agrochemical indicators of virgin soils of the Nyazepetrovsky district
    Postoiko V.N., Nutfullina L.Sh. Federal State-Funded Educational Institution of Higher Professional Education “Ural State Academy of Veterinary Medicine”, Troitsk Zemlya, as an object of habitat for flora and fauna, as well as human economic activity, is part of ecosystems, and therefore should be constantly monitored. Available literature sources indicate that soil conditions are assessed primarily through
