Example Embodiment
[0025] Such as Figure 1 ~ Figure 3 As shown, a deep learning-based atrial fibrillation event detection method of the present invention includes the following steps:
[0026] S1. Obtain the ECG signal (that is, the ECG signal) used to train the deep learning model for atrial fibrillation event detection, and then preprocess the ECG signal to remove interference and invalid data to prevent these interference signals from subsequent data processing Cause adverse effects in;
[0027] Preprocessing operations include: removing high-frequency glitch noise signals through a low-pass filter, removing baseline drift interference signals through a high-pass filter, and removing 50Hz power frequency interference signals through a notch filter;
[0028] S2. Perform QRS detection processing on the preprocessed ECG signal to extract the heartbeat information in the ECG signal;
[0029] QRS detection processing specifically includes the following steps:
[0030] S2.1. QRS heartbeat positioning. Sin...
