Abstract:

    The article shows the results of the implementation of the first stage of the project "Study of the application of new mathematical methods for analysis of cardiac data", funded by the Research Fund. The results are related to the creation of a portable information system for individual monitoring of the cardiovascular system, which includes a portable device for recording photoplethysmographic (PPG) signals and software for processing, mathematical analysis and assessment of heart rate variability. An important advantage of the portable device is the ability to constantly monitor and record the functioning and parameters of the cardiovascular system of the individual. This allows more accurate diagnosis of patients in different life situations in normal life, which is based on subsequent scientific analysis of the registered cardiac information through developed specialized software using linear and nonlinear mathematical methods. The article also shows the results for validation of the created new device, by means of an experimental scheme with which electrocardiographic (ECG) and PPG signals are registered simultaneously. The obtained two types of signals are compared in terms of the accuracy parameter of the registered signals. The results show that the two types of registered signals are identical; therefore the developed portable device can be used as an alternative to the currently widely used ECG and Holter devices.
