FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to a device, method and system for monitoring physiological signals. The method is performed using a device worn by a user. The device is made with the possibility to receive a digitized physiological signal in real time and transmit the digitized physiological signal to a server via a mobile terminal. The user terminal includes a communication scheme for establishing communication with the server. The system includes a server, a user mobile terminal, and a wearable device. When performing the method, samples of the physiological signal are obtained. Events are detected in the physiological signal. Characteristics of detected events are extracted. Search for anomalies is conducted in events and in extracted characteristics of events. In response to the detection of an anomaly, a priority level of processing the detected anomaly is determined among two priority levels. Anomalies of the highest priority level are represented up to anomalies of the lower priority level on an operator terminal. When an anomaly is detected or when an enhanced control mode is activated, the digitized physiological signal is transmitted wirelessly in encoded form to the server. Otherwise, the digitized physiological signal is erased by the device. In another embodiment of the method, the physiological signal includes an electrocardiogram signal. In this case, detected events are impulses R, P, Q, S and T. Extracted characteristics of detected events relate to amplitudes of these impulses and/or to the duration of time intervals between impulses Q and S, P and R, and/or angles of inclination between a vertex and a base of impulses S, T, P. A reference signal is obtained. Characteristics of impulses R, P, Q, S and T are determined in the reference signal. A reference window is determined for each of characteristics. A warning signal is generated if the characteristic extracted from the digitized physiological signal is not located in the corresponding reference window among reference windows determined based on the reference signal.

EFFECT: system, a method and a wearable device are provided for receiving and monitoring physiological signals for long periods, including during sleep and sports activities, while detecting signal anomalies indicating pathology.
