GEOMETRIC PARAMETERS CALCULATION OF ECG LEAD POINTS ON A 3D-MODEL OF THE HUMAN CHEST

Abstract

Background. The study belongs to the direction of personalized medical care and is devoted to determining the geometric parameters of ECG leads in modeling the electrical activity of the heart. The aim of the work is to develop software for calculating the geometric parameters of ECG lead points and visualizing the human chest using a 3D model. Materials and methods. The work uses a three-dimensional model of the human chest, created in the Blender environment. When developing the software, the OpenGL and GLUT graphic libraries, the Microsoft Visual Studio 2017 development environment, and the C++ programming language were used. Results. The developed software makes it possible to determine the intersections of the lead vectors (from the heart to the lead point on the surface of the chest) with objects inside the chest and calculate the corresponding geometric parameters. The performance is demonstrated on 3 different examples. Conclusions. The developed program implements the display of the surface of the human chest, ribs and lungs, the calculation of the geometric parameters of the lead points. The obtained parameters can be used in the process of personalized diagnostics based on the model of the electrical activity of the heart.
