Abstract

The invention relates to a classification method of heart beat based on BiLSTM-Attention deep neural network. The classification method includes the following steps: 1) data pre-processing, using bi-orthogonal wavelet transformation to remove high-frequency noise and baseline drift; 2) feature extracting, detecting R-wave peak value by dyadic spline wavelet transformation, and further calculatingRR interval and extracting QRS wave complex data; and 3) model training, carrying out deep learning and classification on the detected waveform in step 2 through BiLSTM-Attention neural network. The classification method has advantages of accurate and effective classification of electrocardiogram (ECG) signals and deep learning and classification of ECG signals

Description

technical field [0001] The invention belongs to the technical field of heartbeat detection and classification, and in particular relates to a heartbeat classification method based on a BiLSTM-Attention deep neural network. Background technique [0002] Arrhythmia is a symptom of abnormal cardiac electrical activity caused by abnormal frequency or rhythm of cardiac beating due to the origin or conduction blockage of cardiac activity. It is an important group of diseases in cardiovascular diseases. Cardiac activity analysis is the key to intelligently judging various parameters of the human body, and electrocardiography (ECG) is an important means of non-invasive examination and diagnosis of various heart diseases such as arrhythmia, and also reflects the periodic activity of the heart. It is an important indicator and is widely used in clinical practice all over the world. Arrhythmia is an extremely common and very important disease type, and its identification is one of the...
