The problem of excitement in psychology is complemented by a number of social and socio-psychological factors, increasing interest in it. In modern society, intensive social, political and technological changes are taking place, which intensify personality disorders, increase the demands placed on a person, and increase the feeling of uncertainty and excitement in a person [9. etc. 3]. Thus, the symptom of anxiety is the most widespread mental phenomenon. The range of manifestations from the range of excitement varies from adaptive excitement to neurotic excitement, to pronounced mental states of endogenous origin, accompanied by anxiety disorders. This shows that these symptoms occur both in everyday life in most ordinary people and in patients of general therapeutic and psychiatric diseases [8].

The feeling of excitement among high school students currently remains the main factor affecting the quality of life of young people, as well as the qualitative mental and emotional development of young people's personality [3].

Among adolescents with high arousal, the ratio between the processes responsible for affect and inhibition is observed to be disturbed. The imbalance in a person's sense of harmony has an emotional nature, which can now be corrected by transmitting information and exerting pressure from society and social groups [1].

The aim of the study was to determine the changes in vegetative indicators due to the influence of the examination process in 17-year-old choleric students, depending on the typological characteristics of the nervous system.

Materials and methods

The students participating in the research were practically healthy, they joined the research on a voluntary basis. Experiments on those students were carried out taking into account the proposal of the Bioethics Committee of the European Convention (Strasbourg, March 18, 1986).

In order to study arterial blood pressure during all tests, on a normal day, before and after the exam, systolic arterial pressure, diastolic arterial pressure and the number of heartbeats in 1 minute were recorded by the N.S. Korotkov method using a manometer pressure device (Turkey) Microlife BP 3BTO-2 from the automatic brachial area. Vegetative tone was determined based on the results of these obtained indicators. That is, vegetative tone was calculated based on Kerdon's vegetative index

Research results and their dimtahandan sonracussion

On an ordinary day, in 17-year-old choleric students, blood pressure is 111.0±4.8 mmHg, diastolic arterial pressure is 76.0±3.5 mmHg, the number of heart beats in 1 minute is 91.2± 91.2 after the exam. 4.7 was the emphasis. the vegetative index of credo, calculated based on the indicators obtained on a regular day, was 17. At this time, before the exam, sell 7.2% or 8 mm.c.milk. rising to 119.0±2.2 (p<0.05) mm.c. column, diastolic arterial pressure 7.2% or 5.5 mm.c. rising to 81.5±1.6 (p<0.05) mm.c.milk. has arrived accordingly. In that group of students, the number of heart beats in 1 minute increased by 5.7% or 5.2 units to 96.4±6.1 (p<0.05) (Figure).

Credo's vegetative index, calculated based on the hemodynamic indicators obtained before the exam, was =16. The analysis of the results of hemodynamic indicators obtained from the effect of exam stress by groups shows that systolic arterial pressure after the exam decreased by 2.1% (p<0.05), diastolic arterial pressure by 1.4% after the exam compared to the usual school day. Meanwhile, the number of heart palpitations decreased by 8.7% (p<0.05) after the exam. Vegetative index of credo, calculated based on hemodynamic indicators, shows the superiority of the usual day and before the exam.

Figure. Comparison of the dynamics of heart rate and blood pressure in 17-year-old choleric students due to emotional stress during the exam after the exam (%)

After the exam, the systolic arterial pressure significantly decreased from before the exam to after the exam and was 108.7±4.2 (p<0.05) mm.c.milk. is, meanwhile, the diastolic arterial pressure further decreased (8.1%), i.e. it decreased to the normal daily level, i.e. 74.9±1.8 mm.c. The number of heartbeats in 1 minute decreased to the pre-exam level compared to the post-exam level (13.6%) and came close to the normal daily level, corresponding to 83.3±2.5 (p>0.05) heartbeats. According to the noted hemodynamic indicators, Credo's vegetative index was =10, which indicates that the systolic pressure is still in a state of dominance, as in other groups. It should be noted that we compared the results obtained from the study by groups. due to the effect of exam stress, it changes in two phases. so the systolic arterial pressure increased after the exam compared to the usual day. This indicator is 7.2% less than before the exam.

Although the diastolic arterial pressure indicator tends to return to the normal daily level after the examination, certain differences are still not detected. However, its indicator is much lower (8.1%) than the level before the exam. Credo's vegetative index, calculated based on hemodynamic indicators, shows that it is superior in all three cases. Credo's vegetative index proves this superiority of sympathetic tone. There is an honest change in the number of heart beats per minute. The changes in situational and personal arousal level after this examination indicate that the tone of the somatic nervous system has an advantage over the autonomic nervous system indicators.

In those students, there are certain differences between temperaments and age periods in the number of heartbeats before and after the exam, and the number of atolic and diastolic arterial pressure after the exam, that is, there are sharp increases and decreases between these indicators. The dynamics of changes in hemodynamic parameters during the examination characterizes the tense state of the regulation mechanisms of the blood-vascular system after the examination [4-6].

In the CNS, there may be an acceleration of the retardation processes, the development of the body's pre-defense reactions and the full activation of the adaptive processes. According to the vegetative indicators and the Kerdo index, the advantage of SSS was observed in students, which is the result of how important the exam is for young people, the responsible approach to the exam and the activity of adaptation processes [2].

It is known that the increase in the activity of the sympathetic branch of the thymus after cardiovascular surgery activates the adaptive response of the hypothalamus-pituitary-adrenal gland after surgery. The results of the research show that there are differences in the activity of the autonomic nervous system in students of different ages. The analysis of the results of the hemodynamic changes we obtained from the effect of exam stress on groups also shows that the autonomic index of credo is in the state of dominance of the sympathetic tone during the normal day and before the exam [7].

Conclusion

• 1.    Although Credo's autonomic index shows the predominance of the sympathetic tone of the autonomic nervous system on a normal day and after the exam, this indicator is in the predominance of the parasympathetic tone before the exam.

• 2.    After the exam, students' autonomic indicators tend to return to their usual level due to the removal of the stress factor, the main reason for which is the decrease in autonomic nervous system tone associated with fatigue.

• 3.    The vegetative index of students' credo after the exam proves that this advantage is sympathicotonia. it shows the superiority of SSS throughout the post-exam period.
