The aim of this study was to develop a three-dimensional (3D) animation of the heart that can show its components and function using electrocardiography. Another aim of the study was to increase knowledge on computer graphics and animation as well as to create a useful educational tool that, through play, will also teach. Because the heart is one of the most important organs and a very complex one, the authors decided to create a 3D model. This article presents the current state of knowledge in the use of computer-generated models of the human heart as a learning aid and for creating simulation. The authors describe the tools used to implement the program and sources that were used for modeling the heart. The result is presented in the form of descriptions and screenshots on how to use the program. At the end of the article, a description is placed of further developments that will be applied to the program.

This paper focuses on techniques of phonocardiographic image registration. Simultaneous measurements of sound wave amplitudes from above the chest of a healthy person were performed by means of piezoelectric microphones. The location of the source of sound waves can be determined by implementing the size of the amplitudes. Sound source changes its position in time and moves the wheel tracks covering the entire heart or accumulate in some places. A comparison of the results of heart auscultation with an image received by echocardiography was possible due to the fact that the collected phonocardiographic measurements and echocardiographic examination were obtained with ECG sampling. The occurrence of the specific events from the heart auscultation was attributed to their genesis mechanism.
