Background. The problem of combating cardiovascular diseases among the population is acquiring national importance due to the increase in morbidity, high level of disability and mortality from cardiovascular diseases, lifelong, expensive drug treatment, and dictates the need to pay more and more attention to early prevention of these diseases. One of the areas of prevention and diagnosis of cardiovascular diseases, which has become possible due to technological progress, is the mathematical modeling of the electrical activity of the heart. The concept of a digital twin of the heart is based on mathematical modeling of the electrical activity of the heart with all parameters and functionality using digital technologies. The aim of the work is to develop a digital twin of the heart based on equivalent electrical generators of the heart of the surface and dipole types with visualization during the cardiocycle of the state of its electrical activity on the surface of the epicardium for diagnosing violations of conduction processes and the vector of the dipole moment for diagnosing myocardial ischemia. The specified combination of functional capabilities is a distinctive feature of the developed digital twin of the heart based on the equivalent electrical generators of the heart of the surface and dipole types. At the same time, texturing of the digital twin of the heart makes it possible to visualize the myocardial damage revealed as a result of diagnostics.
Materials and methods.The research uses methods of mathematical modeling, intellectual methods of processing and computer visualization of modeling results.
Results and Conclusions. The representation of the digital twin of the heart proposed by the authors makes it possible to visualize the electrical activity of the heart on the surface of the epicardium, which brings (in the presence of diagnostic information) the possibilities of functional diagnostics to those of computed tomography.
