Cardiovascular system performs important functions in the human body. At the same time, according
to statistics of the World Health Organization the diseases of cardiovascular system hold the first
place in the world among reasons of death. In this regard, in medicine of critical states the development
of diagnostic methods of cardiovascular system functioning, including computer-supported technologies,
is very important. In studies presented in this paper, the device, including software for data
processing, is developed for tracking in a continuous mode of the cardiovascular system functioning
of person. The new approach is that the device monitors continuously the heart rhythms of a person
without his or her direct active targeted actions in this area. This eliminates the factors that depend on
the human subconscious and which may affect on the monitoring result. The device, if at some point
in time there are abnormalities in the cardiovascular system, informs the person about this. The system
does not put medically accurate diagnosis, but it is an instrument of early warning. Based on this
information the person has the ability to promptly seek medical attention. The prototype was developed
on the base of Arduino + Bluetooth HC-04. The interface was written in Microsoft Visual Studio
2010. Data analysis is carried out on a PC using MATLAB package.
