Abstract

This invention relates to functional diagnostics. The purpose of the invention is to improve the accuracy of the method. Before the breakdown, a correlation rhythmogram (CRG) is constructed using observations of 100 cardiointervals. When performing a bicycle ergometric test, the CRG is fixed on the 1st minute of work, at the height of the load and in the recovery period on the 10th minute. The CRG is analyzed in the proposed phases. According to the CRG data and the values of the variable functions for various data of the RR intervals, the index of the functional state is calculated in all phases of the observation. The method makes it possible to determine in whom the metered load causes an increase in the functional state. 2 tab. to

The invention relates to medicine, in particular to functional diagnostics. The purpose of the invention is to improve the accuracy of the method.

The method is carried out as follows.

In the case of bicycle ergometry, a correlation rhythmogram (CRG) with an observation period of 100 kDonintervals is constructed, and then the bicycle ergometric test is performed according to a predetermined program; minute After testing, the CRG is analyzed in the proposed phases. According to the CG data, according to the generally accepted methodology and additional values of the variable functions for different values of the RR intervals, the functional state index (IFI) is calculated for each observation in the listed phases.

Example 1. L.Yu.A. 25 years old, practically healthy i, By profession - electric welder. The dynamic load is increased by the bicycle ergometer in 25 W for 3–3 min and 50 W for 4–6 minutes. The recovery period is observed for 10 minutes. I fix the CRG before the beginning of bicycle ergometry on the 1st minute, at the height of the load and on the 10th minute of recovery,

PRI m and p 2, S.A.A. 26 years old, practically healthy. By profession a toolmaker. The study was carried out according to the program, anagyugatna example 1.

The dynamics of the values of the IFS of the heart of both studied are presented in table 2.

The values of the variable functions with the values of the intervals RR 0.75 according to the AWG data are presented in Table 1.

A comparative analysis of the KRG and the IFS, calculated in the proposed observation phases, allows us to make an indication of what Lo.A. high tolerance to physical activity compared with SAA, in which bicycle ergometry causes deterioration of the functional state, while L.Y.A. metered load contributes to an increase in the functional state. Thus, the second subject is characterized by a lower level of physical performance.

The proposed sposb makes it possible to give an assessment of physical performance that is highly correlated with the results crawled in a known manner. In addition, the method is characterized by high sensitivity, accuracy,
