Regulation of a Hemodynamics Adaptation to Ageing
The aim of the investigation is to study a scheme implementation of the vegetative supply of the hemodynamics adaptive reaction connected with ageing. It should be evaluated with hemodynamic parameter variability.
Materials and Methods. 489 healthy people have been divided into 2 age groups: 329 at the age of 20—44 years and 160 at the age of 45—65 years.
The variability values of an average arterial pressure have been recorded. R—R-interval, the highest volume of the heart and the peripheral vessels pulsation amplitudes have been observed as well. The researchers have carried out a spectral analysis on the plane of complex frequencies with a spectral density capacity assessment according to the four regulatory ranges.
Results. The received data allows to assess the regulation mechanisms of such parameters as the highest volume and microvessels pulsation amplitude in different age groups. Moreover, it is possible to figure out the cardiac rhythm and arterial pressure regulation mechanisms considering a probability of the oscillation analysis of the most low-frequency range.
