Abstract

The present invention provides a method and device for processing ECG signals. The ECG signal processing method includes the following steps: S1. Obtain ECG signal x(n) and preprocess it to obtain the first signal, wherein n is different The time series of time,; S2, do differential operation on the first signal to get the second signal y(n); S3, make the second signal y(0)=0, make the second signal y(-n) equal to 0 or the second signal y(n) The second signal y(-n)=y(n), the second signal y(n) is recombined to obtain the third signal to amplify the size of the R wave in the ECG signal x(n). The invention reduces the complexity of the detection algorithm, has high robustness and less dependence on the original data, has high R wave detection precision, low cost and simple implementation.

Description

technical field [0001] The invention relates to the technical field of medical signal processing, in particular to a method and device for processing electrocardiographic signals. Background technique [0002] Physiological signals carrying information about human body functions are always mixed together through complex patterns. In real life, people need to obtain accurate physiological information as an intermediate result to analyze the functional state of the signal source that generates the physiological signals. Among them, the R-wave detection method of ECG (Electrocardiogram, electrocardiogram) signal belongs to the electrocardiogram signal processing. The ECG signal is the performance of the electrical activity of the myocardium on the body surface. It is almost a periodic signal. The R-wave is the main feature of the ECG signal. Some methods for detecting R waves of ECG signals are mainly based on the filter plus maximum value extraction method (PT method for short...
