CARDIOVASCULAR CONTINUUM IN THE RESULTS OF SHORT RECORDING OF HEART RATE VARIABILITY: POSSIBILITIES OF INSTRUMENTAL DIAGNOSTICS

Abstract

The issues of clinical significance and possibilities of using the assessment of spectralanalysis indicators of a short recording of heart rate variability for assessing thefunctional state of patients in accordance with the stages of the cardiovascularcontinuum in non-communicable diseases are described in the article.The aim of the study – to carry out a comparative assessment of the indicators of ashort recording of heart rate variability in respondents with different stages of thecardiovascular continuum in order to increase the effectiveness of measures for theprevention and treatment of non-communicable diseases in Ukraine by improvingtheir diagnosis and prevention through the introduction of modern science-intensivetechnologies into medical practice.Material and methods. 307 respondents were surveyed using the Poly-Spectrumhardware-software complex (Neurosoft, Russia). All of them underwent registrationand analysis of a short recording of heart rate variability. 200 comorbid patients withnon-communicable diseases were divided into four subgroups depending on the stage ofthe cardiovascular continuum and the degree of comorbidity. 107 functionally healthyindividuals (control group) were divided into two subgroups depending on the level ofsports training.Results. A decrease in the electromagnetic power (total and all spectral components)was found in patients with non-communicable diseases, depending on the stage of thecardiovascular continuum. The results of personalized analysis of spectral parametersin all study groups were presented and their medical-clinical interpretation was written.Conclusion. Non-communicable diseases are accompanied by a gradual decreasein the electromagnetic power (total and all spectral components) of cardiac activityin accordance with an increase in the degree of comorbidity and progression of thecardiovascular continuum. The clinical and diagnostic value of a short recording ofheart rate variability as a method for diagnosing a functional state and the expediencyof its use in a comprehensive examination of patients in a clinic of internal diseaseshave been confirmed.
