Example Embodiment
[0023] Specific implementation mode 1: This embodiment provides a method for implementing atrial fibrillation detection based on a deep convolutional neural network, in order to make the original one-dimensional ECG signal applicable to the convolutional neural network structure in the form of processing two-dimensional data , The one-dimensional ECG signal needs to be appropriately transformed to meet the input signal requirements of the deep convolutional neural network. In addition, in the implementation method of atrial fibrillation detection based on a deep convolutional neural network provided by this embodiment, the deep convolutional neural network is constructed based on Caffe, one of the most popular deep learning frameworks. The specific implementation steps are as follows:
[0024] (1) The ECG acquisition equipment is used to collect the continuous ECG data of a single lead of the patient, and the doctor will mark each heartbeat of the ECG data whether there is atrial...
Example Embodiment
[0044] Embodiment 2: This embodiment provides a method for detecting atrial fibrillation based on static wavelet transform combined with deep convolutional neural network, such as figure 2 As shown, the specific steps are as follows:
[0045] Step (1): Read the records in the MIT-BIH atrial fibrillation database.
[0046] Step (2): Perform data segmentation on these ECG records. The duration of each data segment is 5 seconds. Since the sampling frequency of the MIT-BIH atrial fibrillation database is 250 Hz, each 5-second data segment contains 1250 Sampling point. According to the annotation file of the MIT-BIH atrial fibrillation database, a sample category label is set for each 5-second data segment. The basis for setting the label is: if the proportion of the number of heart beats of atrial fibrillation in each 5-second data segment in the entire data segment ≥ 50%, the data segment is marked as atrial fibrillation segment, otherwise it is non-atrial fibrillation segment.
