This paper examines the process of software development to implement the system, working on the devices with Android operating system, which is based on Holter monitoring. Application software has been developed using existing methods of digital data processing, that provides the possibility of real-time monitoring of the user's cardiovascular system with subsequent data transfer directly to a specialist doctor in a format, convenient for data analysis. There was proposed an algorithm for processing data, which is based on a template made up of regular expression metacharacters, that provides fast and accurate sifting of the received data. Binary file that is formed as a result of the algorithm work contains the necessary data for subsequent analysis. At the first stages, the software application installed on the Android device performs the initial analysis of the file and breaks the data into fragments that correspond to time periods of sixty minutes. Thus, twenty-four pieces of data are formed during the day. Based on this data created application builds graphs that illustrate the work of the patient's cardiovascular system, which the user can view. If critical indicators arise in the work of the cardiovascular system, the software application automatically calls an ambulance and sends to the attending physician data for the last forty-eight hours in the format of scatter plots, as the experience of practicing physicians has shown that such plots are the most visual and informative. Also, the attending physician has the opportunity to access the data of Holter monitoring of the user's cardiovascular system at any time, using the terminal part of the application on his Android device.
