SYSTEM AND METHOD FOR AUTOMATED ELECTROCARDIOGRAM ANALYSIS AND INTERPRETATION Russian patent published in 2023 - IPC A61B5/349 

FIELD: medicine.

SUBSTANCE: method for determining the characteristics of an electrocardiogram (ECG) is carried out using a system containing a processing means and an ECG recording device. In this case, an ECG signal is obtained using a recording device. A smoothed ECG signal is obtained by processing means by filtering the noise of the received ECG signal. The first derivatives of the smoothed ECG signal are calculated using the processing means. The characteristics of the ECG are determined using the processing means on the basis of the first derivatives of the smoothed ECG signal. Based on the processing of the distribution of local extrema of the first derivatives of the smoothed ECG signal, a threshold is determined to highlight the range of change of the extrema corresponding to different types of waves. The characteristics of the peaks of the waves of different types are determined based on the selected ranges of extremes and the relative position of the local maxima and minima of the first derivatives of the smoothed ECG signal.

EFFECT: automatic detection of signs of the presence of pathologies in the ECG signal and the critical condition of the patient is provided with high accuracy, noise immunity, reduction of the ECG signal processing time for making decisions in automatic mode, with the possibility of flexible and quick response to changes occurring in the ECG curve during the observation process in the conditions of high variability of the studied signal to build short-term and long-term automated medical prognosis.
