New AI model enhances ECG recognition using domain knowledge

Researchers have developed a new domain knowledge-based graph convolution network for electrocardiogram (ECG) recognition, aiming to improve interpretability in AI healthcare applications. This approach incorporates key PRQST landmarks as domain knowledge and uses a double-stream directed graph to model both spatial relationships among points and temporal dependencies between ECG cycles. Experiments on the First Chinese ECG Intelligent Competition dataset showed the model outperformed state-of-the-art methods, achieving an average F1 score of 88.1% and improving detection for rare categories.
