Embodiment 1
[0013] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for filtering ECG signals for removing ringing, comprising the following steps:
[0014] Step S1, collecting the original ECG signal, and identifying the sudden change in the original ECG signal;
[0015] Step S2, intercepting the mutation segment to obtain a mutation signal, and replacing the mutation segment in the original ECG signal with a replacement segment to obtain a replacement signal;
[0016] Step S3, performing power frequency filtering on the sudden change signal and the replacement signal respectively, to obtain a sudden change filter signal and a replacement filter signal;
[0017] Step S4, splicing the mutation filter signal and replacement filter signal to obtain a complete ECG filter signal.
[0018] The original ECG signal sig_ori is collected by an electrocardiograph or other ECG acquisition equipment, and the sampling rate of the original ECG signal sig_ori in this ...
Embodiment 2
[0041] Embodiment 2 of the present invention provides a computer storage medium on which a computer program is stored. When the computer program is executed by a processor, the method for filtering ECG signals for removing ringing described in any of the above embodiments is implemented.
[0042] The computer storage medium provided by the present invention is used to realize the above-mentioned electrocardiographic signal filtering method for removing ringing. Therefore, the technical effects of the above-mentioned electrocardiographic signal filtering method for removing ringing are also provided by the computer storage medium, and are not repeated here. repeat.
