Modifications of recognition procedures of biomedical signals using shape characteristics for their description and in decision criteria

The order of obtaining and evaluating the effectiveness of modifying the recognition procedures of biomedical signals using the characteristics of their shape for describing observed processes and in decision-making criteria are considered. The presentation is illustrated by an example with three types of signals with their classification - N, A, and V types of QRS complexes in a half-hour ECG recording of the patient.
