Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, specifically, to diagnosis and monitoring of ECG and pulse frequency of a patient. Patient's cardiac activity is monitored. For this purpose, method includes using, located in functional connection, a recording system, consisting of a pulse sensor comprising a pulse wave sensor, first short range radio transmitter, ECG sensor comprising an ECS sensor, sensor of patient's physical activity, as well as second short range radio transmitter, data collection and processing system, including third short range radio transmitter, long-range radio transmitter, performing pickup, analogue-to-digital conversion and accumulation of the patient's physiological signals. Method incudes additionally accumulating patient's physiological signals over a fixed period of time. For every next fixed time interval, parameters of patient's physiological signals accumulated during previous fixed time interval are determined. Method includes identification of obtained pulse rate of patient Pf to interval of permissible values of patient's pulse R P . Detecting distorted areas of ECS of patient. Determining coefficient P d  of ECS distortions of patient. Storing undistorted areas of ECS of patient obtained over fixed time interval. Comparing signal level of patient's physical activity sensor with setting W of level of patient's physical activity. If patient's pulse rate Pf belongs to range of permissible values of patient's pulse rate R p , coefficient P d  of distortions of ECS of patient does not exceed maximum coefficient of distortion of ECS of patient R G , patient's pulse rate Pf and parameters of ECS of patient are transmitted to operational observation station and obtained data are stored. When patient's pulse rate Pf belongs to interval of permissible values of patient's pulse R P , for coefficient P d  of distortions of ECS of patient exceeding maximum value of distortion of ECS of patient R G , patient's pulse rate Pf is transmitted to operational observation station, message is sent to patient to check attachment ECG sensors and obtained data are stored. When patient's pulse rate Pf is outside interval of permissible values of patient's pulse rate R P , coefficient P d  of distortions of ECS of patient less than maximum value of distortion coefficient R G  of ECS of patient, transmitting parameters of ECS of patient of operational observation stations, message is sent to a patient on need to check connection pulse sensor and obtained data are stored. When patient's pulse rate Pf is outside interval of permissible values of patient's pulse rate R P , coefficient P d  of distortions of ECS of patient exceeding maximum value of distortion coefficient R G  of ECS of patient, signal level of sensor of patient's physical activity exceeding setting W of patient's physical activity level message is sent to patient to check attachment ECG sensors and sensor of pulse and obtained data are stored. At level of signal from sensor of patient's physical activity, not exceeding setting W of patient's physical activity level, patient is sent messages on critical state, signal is transmitted warning about critical state of patient, accompanied by data on patient's pulse and parameters of ECS of patient for operational observation station of data and obtained data are stored. 
     EFFECT: method improves accuracy of obtained data of monitoring patient's cardiac activity and speed of investigation, enabling patient's notification on loss or deterioration of contact of recording sensors with patient's body.
