This study reveals the clinical value of the parameter of the total power of the heart in assessing the functional state of the patient. The article is devoted to the expediency of using the method of short recording of heart rhythm variability in Objective Structured Clinical Examination. The purpose of the study was to investigate the total power in patients with noncommunicable diseases based on the results of recording a short record of heart rhythm variability as a promising parameter for assessing the functional state during an Objective Structured Clinical Examination. Materials and methods. An analysis of the total power was carried out based on the data of the short record of heart rhythm variability in 229 people. 43 persons were comorbid patients with coronary heart disease, 111 persons were young functionally healthy non-athletes, 75 persons were professional young athletes. Results. The diagnostic value of the parameter of the total power of the heart was proved. 23% and 21% of patients with non-stationary heart rhythm in the background and orthostatic modes were found. A decrease in total power of various degrees was established in patients, in contrast to control groups. Conclusions. 1) The total power of cardiac activity is a promising, diagnostically valuable parameter for assessing the patient's functional state during an Objective Structured Clinical Examination. 2) Now all the conditions have been formed for the widespread introduction of the method of short recording of heart rhythm variability in the practice of internal medicine doctors.3) The method of short recording of heart rhythm variability can be recommended for use in the clinical examination of patients as a device for improving the individual work of a doctor in order to determine the individual characteristics of the functioning of the heart, determine the risk of cardiac death, and early preclinical diagnosis of emerging pathology.

The COVID-19 pandemic, and later a full-scale war in Ukraine brutally disrupted the well-established traditional medical training not only for university students, but for postgraduates as well. The new limitations of physical presence have accelerated the development of teaching and learning in an online environment that includes both asynchronous and synchronous methods of distance education and the introduction of new techniques to provide new knowledge and foster special skills. Today, following the path of improvement, in which the principle of imitation is the leading one and can cause physical and intellectual stress is not necessary, instead searching for new, more effective methods of educational and cognitive activity of students, which shape the needs of society is becoming a priority. Distance learning methods have passed through a number of technological stages, which, in the end, enable to obtain proper medical education even under the conditions of distancing. Today, asynchronous learning is based mainly on the use of Internet technologies. Independent work during asynchronous learning becomes a starting point, an organizing principle, and a central, leading form of student’s training. Therefore, it is asynchronous distance learning that creates the most effective pedagogical conditions to foster self-education and self-learning abilities and skills in medical interns. The unpredictability of the current predicament causes a rapid and forced transition from the traditional (analogue) method of learning and teaching to a more digital-advanced model, even in conditions where the use of digital tools was not so widespread. The implementation of the digital model should act as a new "stepping stone" for the success of evidence-based medical education in the future. At the same time, this ongoing crisis has serious consequences on medical training, including their psychological well-being and the impact on their academic trajectory. The urgency and the need to adapt to new circumstances were so-called a springboard for introducing innovation into medical education.

This study aims to explore the potential of the Electrophotonic Emission Analysis (EPEA) method as an instrumental approach for studying stress in biomedical research. Specifically, the study focuses on assessing the stress levels of Ukrainian military personnel returning from the front using the EPEA method. Materials and methods: A total of 96 individuals participated in this open, non-randomized, exploratory, non-controlled, comparative study. Among them, 26 were military personnel, while the rest belonged to the comparison groups. The EPEA analysis was conducted using a certified hardware and software measuring device called Bio-Well 2.0 (United States). Results: The study found a significant decrease (p<0.0001) in energy levels, with both the military personnel group (41±4.25 J) and the functionally healthy individuals group (57.38±20.78 J) showing similar results. Among the participants, 62% of military personnel and 95% of patients with non-communicable diseases demonstrated optimal energy levels, while 38% and 5% respectively showed reductions. The stress levels measured were 3.69±0.62 cu for military personnel, 3.69±0.62 cu for functionally healthy individuals, and 3.99±1.17 cu for patients with non-communicable diseases. Conclusions: The EPEA method proved effective in instrumentally detecting increased levels of stress and anxiety in 96% of military personnel, 93% of functionally healthy individuals, and 87% of patients with non-communicable diseases in the study. It is of fundamental importance for scientific and systemic medicine to establish that changes in biophoton emission can be observed in patients with non-communicable diseases, including military personnel. Significant differences in total energy levels were found between patients and functionally healthy individuals, with EPEA results showing 41±4.25 J and 43.86±4.87 J respectively for patients and functionally healthy people (p<0.0001). Electro-photonic emission analysis is a promising, valid, accessible instrumental method for biomedical research.
