Embodiment Construction
[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention and the accompanying drawings.
[0024] Such as figure 1 Shown, a kind of ECG signal processing method facing arrhythmia classification, comprises the following steps:
[0025] S1: Perform preprocessing operations such as R peak detection, heartbeat extraction, and data balance on the ECG to obtain ECG signal segments with a uniform format.
[0026] The R peak is the most obvious sign of a heartbeat in the ECG signal, so the position of the R peak can be used to represent the moment when each heartbeat occurs. In the embodiment of the present invention, the popular Pan-Tompkins algorithm is used for R-peak detection. Then, taking the moment of R peak as the center, select an appropriate number of sampling points ...
