Biorythmological Particulars and Elements of the Desynchronosis of the Central Hemodynamics Parameters in the Students of the Northern Medical Higher Educational Institution

Abstract

The parameters of central hemodynamics in young men and women, junior students of the medical faculty of the Khanty-Mansiysk State Medical Academy were analyzed in this study. Values of cardio hemodynamic indicators and vegetation index Kerdo are obtained by 24-hour monitoring. Arrhythmic type prevailed among boys and girls; the second largest type was evening type; the number of students with morning chronotype was limited. Significant differences in the average values of central hemodynamics parameters were found in groups of the young people of the same sex with different chronotype in the hours of morning rise, the diurnal activity and night's repose. Differences between the representatives of different chronotypes were evident to a greater extent in the girls' groups than in the boys' groups. In the group of youths, joined all chronotypes representatives, desynchronosis of central hemodynamic parameters was evident as ultradian rhythms. We observed more intercalated rhythms in young men with arrhythmic chronotype than in boys with evening chronotype where pulse pressure circadian rhythm also disappeared. In the group of girls, we observed disappearance of pulse pressure circadian rhythm. Girls with arrhythmic and evening chronotypes had disorders in rhythms coherence of systolic and diastolic blood pressure and heart rate that led to the absence of circadian rhythm of pulse pressure.

Inter-Gender Features of Hemodynamics Rhythms in Northerners With Impaired Vegetative Regulation of Arterial Pressure

“…В условиях северных территорий отмечаются гендерные и широтные особенности регуляции функций системы кровообращения [13]. В группах здоровых молодых людей, проживающих в северном регионе, была обнаружена разная степень нарушения хроноструктуры гемодинамических функций у юношей и девушек [20]. Это обосновывает необходимость отслеживать компоненты климатического десинхроноза [10], половых различий биоритмической адаптации [4] и роль лекарственных средств в развитии десинхроноза [11] для комплексной оценки хронома АД в норме и при патологии.…”
