In this article, we study the degree of dependence of heart rate variability in healthy adolescents and young adults on the average rhythm frequency. In the study group, heart rate variability decreased as heart rate grew. Although there was no difference in the increase in the heart rate, the variability ...

A medical examination on a selected group of young people demonstrated a negative correlation between the body mass index and the heart rate at rest, which disappeared after some physical activity. Physical activity was observed to change the heart rate variability under the influence of the changes mag­nitude in the initial heart rate. No correlation between body mass index and ...

Frequency and variability of heart rate served as instruments to assess the stress resistance of two groups of students with different average academic performance in different periods of the educational process: at the beginning and at the end of the autumn semester. Mental stress ...

The authors try to characterize changes in viscosities of blood and throm­boresistance of vascular endothelium after stab wounds of heart. To achieve the goal, the indicators of microblood circulation were studied in 34 patients. All patients were divided into two groups: the first group of 17 people has been operated for the wounds of heart with the thoracotomy, suturing heart wounds ...

... myocardium with a predominant combination of cavity dilatation and hypertrophic left ventricle. One third of patients having endothelial dysfunction have remodelling of the myocardium. It explains a greater frequency of angina pectoris and the development of heart failure symptoms. Persistent remodelling is associated with impaired endothelium-dependent vasodilation; a significant number of patients develop paradoxical vasoconstriction. A combination of these factors largely determines the degree of residual ...

... linguistic and comparative analysis of the concept — suggests that certain Russian idioms containing the concept ‘soul’ have equivalents in the Armenian language. However, in most Armenian equivalents, the ‘soul’ component is replaced by the ‘heart’ mythologeme. In the Armenian language, the concepts of ‘soul’ and ‘heart’ are relatively equal in the scope of information they encode. Moreover, there are words containing the ‘soul’ (հոգի) component that do not have equivalents ...

This paper presents the scope of challenges which are faced in development and manufacturing of the cathode-compensator dedicated for micro-SPTs, and possible ways of how to overcome them. As compared to standard models, such a cathode shall be smaller in dimensions, shall have a lover propellant flow rate, as well as lover heater power and power consumption when self-operated; and it shall be able to operate in the current range of 0.3…1A or lower. 1.
