MSAIC-Net: A Multi-Scale Attention and Imbalance-Aware Contrastive Network for ECG-Based Myocardial Substrate Abnormality Detection
Researchers have developed a new deep learning model called MSAIC-Net to improve the detection of myocardial substrate abnormalities using electrocardiograms (ECGs). This model utilizes multi-scale attention mechanisms and an imbalance-aware contrastive learning strategy to better capture complex ECG patterns and address data imbalances. The network was evaluated on datasets from the University of Virginia Health System and the PTB-XL dataset, showing superior performance compared to existing methods, especially in scenarios with limited data.
