An Information System for Cardiological Data Studying

This paper presents a training information system for studying biomedical cardiological data. The software system examines cardiological data obtained in real conditions (electrocardiographic, photoplethysmographic, and Holter data). The interactive system is oriented toward upgrading the training of students in medicine and health care, providing an opportunity to create a preliminary experience for future medical professionals in working with different types of cardiological data. The use of photoplethysmographic and Holter data is discussed in more detail. The presented system provides an opportunity to conduct research and studies on the interaction between the heart and the functioning of the human organism. The article shows the results obtained in the analysis of cardiac data registered in healthy subjects and patients with cardiovascular disease. Graphical results (Spectrogram and Global Power Spectral Density) from the study of healthy subjects compared with the graphic results of subjects with arrhythmia are presented and discussed.
