The article presents the materials of research of regulatory mechanisms of cardiovascular system functioning in students' youth with different level of risk factors development of cardiovascular diseases (CVD). Psychological factors have become increasingly important in the pathogenesis of CVD. The combination of multiaspects of the problem requires the development of conceptual models of diagnostics, which allow to fully identify and take into account the etiology and pathogenesis of CVD. Depression increases the risk of cardiovascular disease, hypertension and stroke. People with high levels of neurotic disorders are more sensitive to psychosocial stress, have increased blood pressure, atherosclerosis. Neurotic disorders are associated with a high risk of mortality from ischemic heart disease. The aim of this work was to analyze the spectral analysis of cardiac rhythm in male and female students with low, medium and high levels of neuroticism, depres-sion and emotional lability. 108 men and 112 women of 18-21 years old were observed. They were psychologically examined using the form B of FPI test and spectral analysis of cardiac rhythm in klino- and orthostasis did. It was found that the degree of neuroticism, de-pression and emotional lability in men does not affect the functional support of cardiac activity. In women with low levels of depression, orthos-tasis did not show a decrease in the parasympathetic level of regulation. In students with moderate levels of depression, the regulatory mechanisms would be adequate, and at high levels of depression significantly increased % VLF. At low levels of depression, regulatory processes worsen: only % LF increased. The gender difference is as follows. In the klinostasis, girls with low depression had greater % VLF, less % HF, with mean less than % HF, greater % LF; in orthostasis at average, increased % HF, at high – decreased % LF, increased - % VLF. In women, adequate mechanisms are observed only at low and medium values of emotional lability. At high levels of emotional lability, % VLF increased. The gender difference was only in the indicators of persons with an average level of emotional lability in orthostasis: in men, compared with women, higher values of heart rate, % LF, LF/HF, lower % HF. In women with high levels of neuroticism, ade-quate processes for ensuring the functioning of the cardi-ovascular system by the autonomic nervous system have been identified. At low neuroticism, only a significant increase in heart rate was noted. At the average level of neuroticism, an additional increase in % VLF was ob-served, which indicates the activation of higher levels of regulation and is an economical mechanism. The gender difference is as follows. In clinostasis was a higher heart rate in women with high levels of neuroticism compared to men. In orthostasis at low levels of neuroticism in women, less than % VLF, % HF, indi-cating the best regulatory mechanisms in them. At high levels of neuroticism, % LF was lower in women. Conclusions. According to the FPI test, women, compared to men, have significantly higher levels of neuroticism, depression, emotional lability. According to indicators of heart rate analysis in men, the mechanisms of regulation of cardiac activity by the autonomic nervous system do not depend on the level of neuroticism, depression, and emotional lability. In women, adequate mechanisms of regulation are noted at an average level of depression, low and average level of emotional lability, high level of neuroticism.
