[0026] The present invention will be further described below.
[0027] A kind of ECG signal classification method based on the CNN of self-encoding mode and GRU combination, comprises the steps:
[0028] a) Select the MIT-BIH arrhythmia library as the database, and use the lead II signal in the database as the data required for the experiment;
[0029] b) Utilize the computer to remove the P wave and QRS wave in the original ECG signal with a median filter with a width of 200ms, and remove the T wave in the original ECG signal with a median filter with a width of 600ms, Use the original ECG signal to subtract the remaining ECG signal after the P wave, QRS wave and T wave that have been removed by the median filter, to obtain the ECG signal after the baseline drift is removed;
[0030] c) The computer uses a low-pass filter with a cutoff frequency of 35HZ to process the ECG signal after removing the baseline drift, removes high-frequency noise contained in the signal, and obta...
