The initiative group, decided to issue a journal, has over 40 years of experience in biophysical research. With great experience of research from mere suggestion to application of the results in mainstream production, and scientific literature publishing experience, we paid attention to the system contradictions existing in cardiology. Firstly to those ones which significantly hinder progress in cardiology. For example, a clear understanding of the principles of functional cooperation of different parts of cardiovascular system still does not exist in the conventional cardiology. It is due to the lack of theoretical models describing the processes of hemodynamics. Hemodynamic parameters are described in the most archaic way and can not be used in general practice. Standards for diagnosis in electrocardiology are based only on the past experience and show significant contradictions. The term "evidence-based medicine", and namely, its foundation does not stand up to criticism. The system of education in medical universities contributes to such a state of things. Study of the principles of scientific research is not included in medical curriculum, and therefore physicians are not able to identify the cause-and-effect relations of pathology and analyze the effectiveness of therapy in their practice.
Difference of approaches to the theories between physicians and engineers of medical equipment significantly affects the development of cardiology. It results that no measurement criteria and basic metrology in cardiology are available. The existing journals in cardiology are very narrowly focused. It does not promote the proper understanding of the issues by the cardiologists in their fields, and especially their perception of new developments in related fields. The nomenclature of the European cardiology journals, as well as the U.S. ones, is very diverse. Despite all this, they often publish articles of the same type, making it difficult to identify anything of the innovative sort in cardiology. But none of the existing journals deals with measurements in cardiology and especially metrology.

Aims This paper deals with solving of a century-old paradox of linear stability for the Hagen-Poiseuille flow. A new mechanism of dissipative hydrodynamic instability has been established herein, and a basis for the forming of helical structural organization of bloodstream and respective energy effectiveness of the cardiovascular system functioning has been defined by the authors. Materials and Theory of hydrodynamic instability, Galerkin’s approximation. methods Results A new condition Re > Rethmin » 124 of linear (exponential) instability of the Hagen-Poisseuille (HP) flow with respect to extremely small by magnitude axially-symmetric disturbances of the tangential component of the velocity field is obtained. The disturbances necessarily shall have quasi-periodic longitudinal variability along the pipe axis that corresponds to the observed data. Conclusion We show that the obtained estimate of value of Rethmin corresponds to the condition of independence of the main result (on the linear instability of the HP flow when Re > Rethmin) from the procedure of averaging used in the Galerkin approximation. Thus, we obtain the possible natural mechanism for the blood swirling flows formations observed in the aorta and the large blood vessels.

Aims 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 responsible for the maintenance of the hemodynamic parameters within the norms are presented in this paper. Materials and A change in the form of an ECG phase segment reflects qualitatively the methods actual contraction performance of the respective cardiac muscle part involved. In case when the contraction of a cardiac muscle part is weak, an adjacent part undertakes the required compensation function in order to adjust the process. The causality analysis allows identifying the primary cause of a pathology which makes impossible to maintain the proper phase-related blood volumes within the norms. Results An evaluation of the hemodynamic self-regulation mechanism on the basis of the analysis of the compensation mechanism responsible for the maintenance of the hemodynamic parameters within the norms allows revealing the primary cause of the cardiovascular system pathology. Conclusion We offer an innovative methodology that is easy to use and very efficient, therefore, it can be widely applied in practice.

Aims This paper deals with a study of central hemodynamics in 363 pediatric patients with burn shock as compared with a reference healthy children group in order to establish clinical value of the hemodynamic parameters for burn shock diagnostics and therapy. Materials and There is a new method applied to examine the functional status of the methods cardiovascular system with use of the medical equipment Cardiocode that is based on the method of the heart cycle phase analysis and capable of measuring parameters such as a stroke volume (SV), a circulation minute volume (CMV), systolic parameters (both a rapid ejection volume Vr.e. and a slow ejection volume Vs.e.), diastolic parameters (an early diastole volume Ve.d. and an atrial systole volume Va.s.), including a volumetric parameter characterizing the actual tonus of the ascending aorta (Va.a.). Results Age-related trends in the above volumetric parameters have been established herein. Specific features of the hemodynamic parameters in pediatric patients with burn shock have been identified. Conclusion Diagnostics of changes in the central hemodynamics in pediatric burn patients at their hospital admission provides reliable prediction tools for detecting shock well in advance and starting with an adequate intensive therapy.

Aims 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. Materials and An anti-androgenic drug was used by a patient as prescribed for prostatitis methods therapy. A week later upon taking the drugs, it becomes necessary to make an additional diagnostics of the patient to complete the basic diagnostic evaluation. The reason was that upon taking the drugs there were some cases of loss of consciousnes reported by the patient. During an examination by the treating physician, it was found that there was a syndrome of cold limbs in the patient. For the purpose of the additional diagnostics, the method of the heart cycle phase analysis was applied. Results The heart cycle phase analysis allowed identifying the primary cause of the patient’s health degradation and cases of loss of consciousness. Conclusion It was revealed that the primary cause was a side effect of the anti- androgenic drug that led to a decrease in the hemodynamic parameters, resulted in blood vessel failure to transport the necessary quantity of oxygen to tissues in the organism. The recommendations given upon the diagnostics were aimed at recovering the transport function of the blood vessels. By complying with the recommendations, the health status of the patient was recovered, and loss of consciousness was no longer observed.

Aims The response of the cardiovascular system to acupuncture treatment is studied in the present paper. Materials and In the process of study a special device for recording hemodynamic methods parameters as well as the classical acupuncture method was used. The hemodynamic parameters were recorded at the time of needle insertion, during the acupuncture session and after the session. Results The changes in the phase blood volumes were recorded. The influence of the acupuncture on the muscle contraction amplitude during all phases of the cardiac cycle was recorded. Conclusion Appliance of the cardiac cycle phase analysis enables accurate monitoring of the response of the cardiovascular system to acupuncture.

Aims 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. Materials and An original ECG lead of the ascending aorta is proposed. It identifies the methods boundaries of the rapid and slow ejection phases. The concepts and description of the ECG waves are introduced. The amplitudes of the ECG waves are used to characterize the contraction of the muscles of the cardiovascular system segments. Results The general principles of the ECG standardization based on the amplitude analysis of the ECG waves are described. Conclusion Development of the standardization system will contribute to quality improvement of the diagnostics performed by practising physicians.
