Abstract: In order to be able to accurately detect R waves, this article introduces a wavelet transform algorithm to detect R waves of ECG signals. The algorithm mainly uses discrete wavelet transform to have the characteristics of multi-resolution analysis, that is, multi-scale analysis. It uses db1 wavelet, uses its unique time-frequency domain characteristics, uses Mallat fast algorithm to decompose the signal into multiple scales, and then according to the wavelet transform modulus maximum The relationship between the value and the mutation point of the original ECG signal is used to detect the R wave. This article extracts the ECG signal from the MIT/BIH database, filters it through a digital filter, and then performs wavelet transform. Experimental results show that the algorithm can accurately and effectively locate R waves, and the accuracy of R wave detection is achieved. . . <br><br>Keywords： ECG signal wavelet transform multi-resolution analysis filter R wave detection

Abstract: In order to detect R-waves accurately, this paper introduces an algorithm for detecting CST R-waves by small wave transformation. The algorithm mainly uses discrete wave wave transformation with multi-resolution analysis, i.e. multi-scale analysis, uses db1 wave, uses its unique time-frequency domain characteristics, uses Mallat fast algorithm to break down the signal into multiple scales, and then detects R-wave according to the relationship between the large value of the small wave transformation module and the original CST mutation point.
