A 1D Transformer network effectively classifies heart disease and arrhythmias using ECG and clinical data, highlighting the utility of attention mechanisms in biomedical time series.
Early prediction of cardiovascular disease remains a critical public health challenge.This paper presents a 1D Transformer-based architecture for classifying patients as healthy or suffering from heart disease using ECG signals and clinical data.The model is evaluated on three benchmark databases: Cleveland Heart Disease (tabular data, 303 patients), PTB (ECG signals, 290 patients), and MIT-BIH (multi-class arrhythmia, 48 patients).Our approach achieves accuracies of 88.5% ± 1.2 (Cleveland), 94.2% ± 1.5 (PTB), and 89.2% ± 1.8 (MIT-BIH).The PTB dataset shows strong discriminative performance (AUC = 0.97), while Cleveland achieves AUC = 0.94.For MIT-BIH, class imbalance mitigation improves macro F1-score from 0.47 to 0.69.These results demonstrate the effectiveness of attention mechanisms for modelling biomedical time series, while highlighting the critical importance of proper validation protocols and imbalance mitigation for clinical applications.
