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 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.

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.

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.

A cardiac muscle performance assessment in terms of acid-alkaline balance has never been carried out before. The studies show it is possible to evaluate indirectly aerobic, anaerobic and phosphocreatine processes in the cardiac muscle using ECG only. The aim is to study the capabilities of acid-alkaline balance measurement in the cardiac muscle using ECG only, in combination with the heart cycle phase analysis.

The phase characteristics of a rheogram are described in literature in general only. The existing theory of impedance rheography is based on an analysis of the form of rheogram envelopes, but not on the phase-related processes and their interpretation according to the applicable laws of physics.

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.

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.

There has been a significant interest in recent times in discussing how to properly interpret the diagnostic value of the point J on ECG. At first sight, it might appear to be a rather simple issue, but till now no consensus in its interpretation has been reached.

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.

A shortcoming common to all existing designs of mechanical cardiac valve prostheses is an increased trombogenicity caused, among other factors, by the lack of hydrodynamic compatibility between the luminal part of the prosthesis and the patterned blood flow. The aim of the study is to design and test our new mechanical aortic valve prosthesis to exclude life-long anticoagulation treatment.

Conventional methods for arterial pressure (AP) measurement are not capable of identifying it in each cardiac cycle. Besides, they ignore many significant factors. The paper reports on an innovative method based on cardiac cycle phase analysis for detecting systolic and diastolic AP changes in each cardiac cycle using synchronous digitally processed ECG and Rheo recordings. Considered is the phase mechanism of the natural diastolic pressure regulation. The diastolic AP changes referred to the physiological norm and aortic dilatation status are also assessed.

This paper describes a novel approach to the analysis of electrocardiographic data based on the consideration of the repetitive P, Q, R, S, T sequences as cyclic codes. In Part I we introduce a principle similar to the syndrome decoding using the control numbers, which allows correcting the noise combinations.

This is an overview aimed at a detailed interpretation of the concept of identification of boundaries in each cardiac cycle, and first it is directed to justification of an introduction of new points on an ECG curve, namely, point L as the end of the blood rapid ejection phase and point Z as the moment of reaching energy balance of myocardial muscle contraction determining the ECG isoline.

Breast cancer (BC) takes a leading position among all malignant neoplasms in women. One of the critical aspects of the radical treatment of BC is the development of post-castration syndrome (PCS) in patients of reproductive age, who as a rule reach physiological, social and professional maturity, competence and status in the period up to 45 years of age.

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.

The article briefly discusses the cardiometric approach to the evaluation of metabolic processes in cardiac muscle. Reactions occurring during the various phases of the cardiac cycle, primarily in the QRS complex, are shown. The dynamics of energy processes occurring before and after physical load, as well as the reactions occurring during it, are presented. The ECG derivative is used.

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 objective is to demonstrate the features of an original mathematical model of hemodynamics, developed by Russian researchers G.Poyedintsev and O.Voronova.

The aim is to study the action and effects of antitumor polychemotherapy (PCT) with Anthracyclines on the cardiovascular system performance in primary oncological patients with breast cancer (BC).

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.

Studies of hemodynamics in critical patients under intensive care unit conditions have been a very difficult task until now [1]. There are a number of reasons for that. No instruments capable of noninvasively recording data on hemodynamics and metabolism, as well as the cardiovascular system performance, could be used.
