AI Technical Summary

Technical Problem

In dynamic daily life situations, portable wearable ECG monitoring devices are prone to misinterpreting noise signals as R-peaks or having the true R-peaks submerged in noise and not being identified, resulting in low peak detection accuracy.

Method used

By performing signal enhancement operations such as differentiation, square amplification, and moving window integration on the electrocardiogram signal, key features such as the R peak are highlighted. Combined with threshold screening and signal calibration, the R peak is accurately located, and the window is adaptively adjusted using the time difference between adjacent R peaks to search for the P peak and T peak.

Benefits of technology

It improves the detection accuracy of R peak, P peak and T peak in ECG signals, reduces noise interference and positioning error, and enhances the accuracy of ECG signal peak detection.

Abstract

This application discloses a method, electronic device, storage medium, and program product for detecting electrocardiogram (ECG) peaks, relating to the field of biomedical signal processing technology. The method includes: acquiring an ECG signal and performing enhancement operations on the ECG signal to obtain an enhanced signal, wherein the enhancement operations include differentiation, square amplification, and moving window integration; identifying waveform peaks in the enhanced signal whose peak values ​​exceed a preset R-peak threshold as R-peaks, and determining the location time point corresponding to the R-peak in the enhanced signal as the initial time point of the R-peak; and determining the location time point corresponding to the local maximum value of the ECG signal within a preset first time range as the calibration time point of the R-peak, wherein the first time range is the time range centered on the initial time point of the R-peak. This application achieves high-precision R-peak detection and time localization while maintaining strong noise immunity through signal enhancement, initial threshold screening, and fine calibration of the original signal.
