“THE HEART KNOWS ALL ABOUT US”: AN ASSESSMENT OF THE FUNCTIONAL STATE OF PATIENTS BY THE INDICATORS OF A SHORT RECORDING OF THE HEART RATE VARIABILITY

Abstract

This article highlights the issues of using a hardware technique for assessing the functional state of patients by indicators of a short recording of heart rate variability. The aim of the study is to assess the clinical and diagnostic capabilities of a short recording of heart rate variability in displaying systemic informational energy processes of the human body to increase the effectiveness of measures for the prevention and treatment of non-communicable diseases in Ukraine by introducing the latest science-based technologies into medical practice. An open-label, nonrandomized controlled trial was performed. We studied the wave characteristics of the heart rate in functionally healthy individuals (group 1, n=104) and patients with coronary heart disease including exertional angina, myocardial infarction (in the subacute period) and comorbid pathology (group 2, n=66) by the method of short recording of heart rate variability using spectral analysis and variational pulsometry. The study has demonstrated coronary heart disease is accompanied by a decrease in the overall activity of regulatory systems, inhibition of the energy level of the heart (TP=931.8±710.4 at a rate of 3466±1018 ms²), a low level of hormonal modulation of regulatory mechanisms (VLF=527.3±502.1 ms², which is <700 ms²), depletion of energy resources, a low level of recoverable (HF=205.7±261.8 ms², which is <300 ms²) and mobilization (LF=198.9±191.7 ms², which is <300 ms2) potentials, an imbalance of the mechanisms of neuro-humoral regulation of cardiac activity, a decrease in the resources of cardiac activity VLF=56% when normal values are within 30-50%; VLF>HF+LF), in a state of pronounced distress (SI=256.7±264.7; SI=325.2±297.7; PAPR=71.76±30.3). Using the method of short recording of heart rate variability can allow doctors to determine the current state of physiological circulatory mechanisms, adaptive responses, diagnose maladaptive disorders, stress, monitor the effectiveness of prevention of noncommunicable diseases in respondents.
