In the paper, we consider an algorithm for analyzing a person's heart condition. This algorithm is intended for systems of wireless electrocardiosignal transfer to the supervision and analysis center. Such systems are very useful when it is necessary to promptly estimate condition and operation work of the heart. Thus, more thorough analysis can be carried out later.

These systems can be successfully used in medicine of accidents (ministry of emergency rescue) while evaluating condition of vehicle drivers, of sportsmen during training, of people at home.

It is especially important to detect various kinds of cardiac arrhythmias at early stages. In our work, we have developed the block diagram of algorithm detecting the basic kinds of cardiac arrhythmias using logical formulae.
