Why the study?
Deep learning has shown promise for automated arrhythmia detection, but classification across many arrhythmia classes using residual structures and channel attention mechanisms requires further development.
Does the proposed CNN-based network with global channel attention and short residual blocks improve the classification of 45 cardiac arrhythmia classes from 12-lead ECGs compared to existing models?

A novel 1D CNN architecture incorporating global channel attention and short residual blocks effectively classifies 45 distinct cardiac arrhythmias from 12-lead ECGs, outperforming baseline deep learning models.
May advance automated multi-arrhythmia ECG analysis; extends CNN methods but leaves clinical validation and adoption open.
Electrocardiogram is a non-invasive, inexpensive, and widely used diagnostic tool for arrhythmia diagnosis in clinics. Deep learning techniques have shown great promise in electrocardiogram signal analysis, enabling automatic and accurate detection of various cardiac arrhythmia. This paper proposes an automated multi-label cardiac arrhythmia classification network based on a convolutional neural network. The network aims to detect and classify 45 different cardiac arrhythmia classes using 12-lead electrocardiogram data. Unlike previous studies, our approach incorporates both the residual structure and channel attention mechanism. Thus, we developed two key schemes to improve classification performance: the Global Channel Attention Block and the Short Residual Block. The Global Channel Attention Block incorporates dilated convolutions to preserve overall features. It focuses on the important characteristics of each arrhythmia class from the original electrocardiogram data during the training process. The Short Residual Block employs a residual structure to enhance classification accuracy. The network’s performance is evaluated using a large-scale 12-lead electrocardiogram database for arrhythmia study on PhysioNet and the 2018 China Physiological Signal Challenge dataset. In particular, the proposed classification network shows the highest scores in average precision, recall, F1 score, area under the receiver operating characteristic, and accuracy compared to existing convolutional neural network-based arrhythmia classification networks in a large-scale 12-lead electrocardiogram database for arrhythmia study on PhysioNet.
