APPLICATION OF MORPHOLOGICAL ANALYSIS OF ARTERIAL OSCILLOGRAPHS FOR EVALUATION OF DYNAMICS OF HEMODYNAMIC INDICATORS IN МARTINE-КUSHELEV SAMPLE

Abstract

Summary. The Martine-Kushelevsky test (20 squats in 30 s) is a simple, highly informative method of studying the state of the cardiovascular system (CVS), successfully used for many decades. The use of electronic tonometers makes it possible to improve the method, record heart rate, blood pressure (BP), blood pulsations throughout the study, to assess in more detail the features of the CVS.

The aim of the study – to learn the functional ability of CVS to adapt to the compression of the vessels of the shoulder when measuring blood pressure at rest, after the Martin-Kushelevsky test using (proposed by the authors) morphological analysis of arterial oscillograms (AOG) and justify its informativeness.

Materials and Methods. 105 people aged 18–55 were examined, without any health complaints. The indicators of both the sample itself and AOG, registered before, after exercise, after 3 minutes of rest, were studied. The morphological data of AOG were evaluated (according to the criteria proposed by the authors) according to a five-point system. The results are comparable.

Results. The best, type 1 (28%) and 2 (53%) of AOG were most often registered at rest. After exercise – type 3 (54%), which increased by 37 % due to a decrease in the percentage of AOG type 1 and type 2. After 3 minutes of rest (even with the normotonic type of reaction) AOG had dynamics in the direction of "improvement" and "deterioration". Often, in cases when the digital indicators of the sample differed slightly from each other, a variety of types of AOG were registered. Most often – with an inadequate blood pressure response. It is noted associated with different levels of adaptive capacity of the neuro-reflex mechanisms of blood circulation to compression and loading, viscoelastic properties of the vascular wall, which is confirmed by morphological analysis of AOG.

Conclusions. The use of morphological analysis of AOG during the Martine-Kushelevsky test makes it possible to assess in more detail the state of hemodynamic processes of the subjects, their level of health and adaptive capacity, to diagnose the initial deviations from normal.
