The Functional State of Students of a Medical University according to the Analysis of Heart Rate Variability and Central Hemodynamics

Abstract

Introduction. Prevention of cardiovascular diseases in young people is a key factor of adults’ health care and increase of their life. The purpose of the current investigation was to use indicators of variability of heart rate as a marker of prognosis of risks of cardiovascular pathology in practically healthy young people. Materials and methods of investigation. 63 students (21 young males and 41 young females) at the age of 18–23 years (median age: 20.0 ± 0.15 years) were involved in the investigation by means of cardiorhythmography, registration of blood pressure, calculation of striking power and minute volume, and peripheral vascular resistance. Complex evaluation of the cardiovascular system of medical students of higher medical schools was performed. Results and discussion. Differences in the structure of heart rates as well as rates in correlative connections of heart rhythm between separate rhythms as well as connections of indicators of heart rates with integral indicators of hemodynemics are thought to be connected with the primary type of vegetative regulation. Conclusions. Evaluation of vegetative regulation of heart rhythm in combination with vegetative of hemodynemics allows to determine predisposition to development of cardiovascular diseases in the above mentioned people.
