There are various indications for a mechanical circulatory support (MCS) devices implantation. We report a case of the use of…

In the suggested here linear theory of hydrodynamic instability of the Hagen - Poiseuille flow it is counted the possibility…

A cardiac muscle performance assessment in terms of acid-alkaline balance has never been carried out before. The studies show it…

Conventional methods for arterial pressure (AP) measurement are not capable of identifying it in each cardiac cycle. Besides, they ignore…

The article considers the development of the periodic table of ECG phase changes which should reflect the variety of the ECG curves and can be used as reference system for diagnostics purposes.

Up to the present, ECGs have been classified on the basis of the analysis of the ECG curve shape. But this made impossible to classify many ECG shapes. The most promising methods for the classification must evaluate each of the 10 cardiac cycle phases both by their functions and hemodynamic parameters. The aim hereof is to develop the new classification principles for all possible ECG shape variations.

Basic criteria of finding the markers of the hemodynamic self-regulation mechanism on an ECG and a Rheogram are described herein. The basics of an analysis of the compensation mechanism responsib le for the maintenance of the hemodynamic parameters within the norms are presented in this paper.

The aim is to determine interaction of risk factors (volume of ingested food and exogenous alcohol) and their effects on thermal regulation of a body due to the changed activity of biochemical reactions of neuromediator regulatory systems, related to the synthesis of endogenous alcohol.

The paper presents some interesting data and findings on the study of the performance of the cardiovascular system in long-living individuals aged over 90. In this case, highland area individuals of this class are compared with those in flatland areas.

Some results obtained in recording and processing of phonocardiograms are presented herein. To process phonocardiographic signals, a cascade filtration method has been used that allows detecting tones of the cardiovascular system in the background noise. The effectiveness of the proposed processing method is demonstrated by the results of visualization.
