Introduction. The diseases of cardiovascular system lead in the structure of morbidity. The absence of timely treatment leads to severe complications, invalidity and death of the patient. Only preserving medicine can radically change this situation. Fasegraphy is one of perspective directions in cardiology, that allows even by simplified way of ECG registration to detect early signs of disease development.
Purpose. The development of method of fasegraphy for building of complex telemedicine system for mass prophylactic examinations based on client-server architecture and realization of mobile applications for patients and physicians in Android environment is proposed.
Methods. The portable sensor is used for registration of ECG signal, that provides the transfer of digital data through Bluetooth to the patient’s application. The application provides preprocessing of signal, the control of dosed exercise, stress and transfer data to server. The client’s applications are developed in a java programming language version 7 together with Android sdk. The software of server is written in Java version 8 in conjunction with frameworks Spring 4.3 for REST API and Hibernate 5.1 as ORM. The database is based on MySql 5.5.
Results. The server software provides automatic selection of ECG with atypical cycles for which the physician must pay attention primarily. The algorithm of selection is based on the analysis of ordered Hausdorff distances between trajectories of cycles on the phase plane. When the information about detection of atypical cycles is received, the physician may view ECG, perform additional analysis those ECGs and send appropriate recommendations to patient.
Conclusions. Client-server organization of interaction of physician and patient increases the effectiveness of screening surveys and optimizing time spent by a doctor on the medical services to their patients.
Keywords: client-server system, fasegraphy, distant monitoring, atypical cycles of ECG.
