GAF-FusionNet provides a highly accurate multimodal approach for ECG classification by adaptively fusing temporal and spatial features.
Electrocardiogram (ECG) analysis plays a crucial role in diagnosing cardiovascular diseases, but accurate interpretation of these complex signals remains challenging. This paper introduces a novel multimodal framework(GAF-FusionNet) for ECG classification that integrates time-series analysis with image-based representation using Gramian Angular Fields (GAF). Our approach employs a dual-layer cross-channel split attention module to adaptively fuse temporal and spatial features, enabling nuanced integration of complementary information. We evaluate GAF-FusionNet on three diverse ECG datasets: ECG200, ECG5000, and the MIT-BIH Arrhythmia Database. Results demonstrate significant improvements over state-of-the-art methods, with our model achieving 94.5%, 96.9%, and 99.6% accuracy on the respective datasets. Our code will soon be available at https://github.com/Cross-Innovation-Lab/GAF-FusionNet.git.

Qin et al. (2025) studied Arrhythmia (n=114,646). GAF-FusionNet vs. State-of-the-art machine learning methods (e.g., Multi-Scale CNN) was evaluated on Classification accuracy on the MIT-BIH Arrhythmia dataset. GAF-FusionNet achieved 99.6% accuracy on the MIT-BIH Arrhythmia dataset, outperforming state-of-the-art methods for ECG classification.
