Abstract

The purpose of our work was to study the features of autonomous regulation of cardiac rhythm in young people aged 18 to 22 years with high blood pressure. 135 people were examined and divided into 6 somatotypes according to anthropometric indicators. Spectral analysis of cardiac rhythm and cardiointervalography by Baevsky were performed for each subject using the computer program complex “Spectrum +”. Young subjects with the endomorphic component prevalence were diagnosed with a reduction in the autonomic nervous system tonus. Their total spectral power (2901.2 ms2) was lower compared to subjects with ectomorphic somatotype (8587.1 ms2). Decreasing in the influence of the parasympathetic part of the autonomic nervous system on the regulation of the cardiac rhythm was observed in the individuals with the endomorphic somatotype. Such conclusions were based on the lower power of highfrequency waves (844.9 ms2) compared with ectomorphs (1975.4 ms2). The value of the stress index, obtained by cardiointervalography, in individuals with predominance of the endomorphic component, was higher (161.3 units) than that of persons with an ectomorphic somatotype (35.5 units). It may indicate a significantly higher level of cardiac rhythm centralization in surveyed. The results obtained in subjects with prevalence of mesomorphic type (endo-, ectomesomorphic component) had an intermediate result in the spectral analysis and cardiointervalography compared with the endo- and ectomorphic somatotypes.

Keywords: blood pressure; arterial hypertension; somatotype; mathematical analysis of heart rhythm; autonomous nervous system.
