[0058] like figure 1 shown, including the following steps:
[0059] Step 1: Obtain two training databases, an atrial fibrillation training database and a non-atrial fibrillation training database, and perform data processing on the atrial fibrillation training database;
[0060] Said step 1 includes the following sub-steps:
[0061] 1-1: Obtain two training databases: atrial fibrillation training database and non-atrial fibrillation training database. Trembling ECG data;
[0062] 1-2: Perform denoising processing on each lead ECG signal in the atrial fibrillation training database; the denoising processing on the lead ECG signal in step 1-2 includes the following processing:
[0063] Use median filter to filter out the limit drift in the original ECG signal;
[0064] Use Butterworth digital band-stop filter to filter out the power frequency interference in the original ECG signal;
[0065] A Chebyshev digital low-pass filter was used to filter out myoelectric interference...
