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.
Description of rapid and slow ejection phases in the cardiac cycle.
The response of the cardiovascular system to acupuncture treatment is studied in the present paper.
This paper treats general problems of metrology and indirect measurement methods in cardiology. It is aimed at an identification of error estimation criteria for indirect measurements of heart cycle phase durations.
Capabilities of the cardiometric diagnostics based on the heart cycle phase analysis for identifying the primary cause of a disease are considered in this paper.
Criteria of identification of individual heart cycle phases according to an ECG curve are described in this paper.
Problems of validation and verification are very critical in medicine. The absence of adequate models describing biophysical processes in the organism leads to using only practical evidence for these purposes that hinders innovations. But advances in medicine require new effective ways to solve these problems. Cardiometry as a new field in cardiology offers a new philosophy of validation and verification based on the classical proof theory borrowed from natural sciences. The aim hereof is to provide a new methodology for validation and verification for cardiovascular diagnostics.
The article aims at describing the basic system criteria of the ECG interpretation on the basis of the cardiac cycle phase processes as well as systematizing these criteria for developing new standards for the ECG classification.
The article aims at describing the basic principles of cardiometry – a fundamentally new scientific field which enables the accurate measurement of cardiovascular system parameters.
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 article aims at describing the theoretical principles of cardiometry as a fundamentally new scientific field which enables the accurate measurement of the cardiovascular system parameters.
The interrelation between hemodynamic changes, functions of the cardiovascular system and biochemical reactions in the cells of the heart muscle is investigated in the present paper.
Attempts to create an artificial heart were highlighted by our journal one year ago. Now we can say that there is no break-through news in this field: no technological progress, no pioneering research and no spectacular advancements are reported.
The article is devoted to a novel noninvasive measurement of parameters of metabolic processes in the cardiac muscle fiber cells upon an original ECG processing. Theoretically substantiated is an original method of the ECG cardiac cycle phase analysis, which allows measuring the concentration of oxygen, lactate and phosphocreatine in arbitrary units in the cardiac muscle fiber cells in each cardiac cycle.
The article presents the results of an experimental study of the cardiometric detection of a person’s emotional reactions to verbal, audial and visual stimuli.
The article presents the results of an experimental study on the use of cardiometry and oculography to detect concealed information. It has been shown that a complex assessment of the person’s emotional-cognitive state based on cardiometric and oculographic recording of reactions to specially selected stimulus material of visual and audial modality can be successfully used in concealed information detection.
The paper offers some results from our experimental studies to determine validity of a complex performance fingerprint: the Baevsky stress index used to assess effectiveness of training programs: training sessions targeted at formation of phsychosomatic self-regulation skills and visual & verbal practical training course aimed at development of emotional intelligence.
The new high-tech era begins not with supply of an innovative product to the market, but rather with an intellectual leap in the field of open issues in fundamental engineering, healthcare and education. In the present essay, an example of the successful translation of mathematical, physics- and engineering-related philosophy into the digital platform of Cardiometry is discussed. The theory of hemodynamics, the laws of axiomatics, logic and adaptation can be expressed in terms of mathematics. The original analytical software used in PC-assisted device Cardiocode allows carrying out a phase analysis of the hemodynamics within an extended range.
The article presents experimental evidence of the validity of the hypothesis that theoretical construct “ego state”, in addition to the psychological content, actually reflects the physiological mobilization of a human individual to provide a certain type of response. It is shown that the mobilization is manifested in a certain specific pattern inherent to the cardiovascular system performance.
Cardio-oсulometric indicators to grade psychophysiological readiness of students to examinations are described herein. Given is an experimental evidence that transitions from a low level of psychophysiological readiness of students to examinations to a high level of such readiness thereto is really accompanied by significant changes in the organism performance, first of all, in that of the heart. It is shown that a reliable marker of such changes is the heart rate variability assessment using the Baevsky stress index (SI), as well as the oculometric peculiarities of response to the visual stimuli, which students associate with their upcoming examinations.
The paper presents our experimental evidence of validity of our hypothesis that definite, substantively different, psychophysiological states of a human individual can be really fixed with the use of metaphoric associative cards, and that transitions from one psychophysiological state to another are accompanied by significant changes in the performance of the human organism, and, first of all, in the performance of the heart.
