用手机拍张纸质心电图，ECGLight直接在本地CPU跑30秒就能筛查心梗，准确率95%以上，偏远地区也能用。
ECGLight是一个端到端轻量级框架，可在CPU上30秒内将手机拍摄的纸质心电图转化为数字化12导联信号。该框架在21,799份PTB-XL数据集上训练，并在医院ECG-Matrix数据集上验证。在PTB-XL上心梗检测准确率达95.51%（F1=0.9519），在ECG-Matrix上OMI检测准确率达88.89%（F1=0.8862）。框架还集成SHAP可解释性，支持临床诊断。
ECGLight: Compute-Light Framework For Paper ECG Digitization and Myocardial Infarction Screening
Electrocardiography (ECG) is one of the most widely used tests for diagnosing cardiovascular disease. Yet several remote clinics still utilize paper ECG printouts for their analysis due to limited connectivity and computational capacity. As a result, vast numbers of physical ECGs obtained in remote areas still remain incapable of being accessed by contemporary artificial-intelligence (AI)-based decision support as they require high computational resources or strong high-speed internet connectivity. This causes several cases where conditions like acute coronary occlusion (ACS) is overlooked and reperfusion therapy delayed. Although prior work has tackled digitization and diagnosis separately, and utilized advanced AI models for them, there still remains a lack of a compute-light, on-device framework that reconstructs paper ECGs at high fidelity, while accurately supporting multiple clinically relevant endpoints. We address this need with an end-to-end lightweight on-device digitization-to-diagnosis pipeline that converts a smartphone photo or scan of a paper ECG into a calibrated 12-lead signal and screens for Myocardial Infarction (MI) pathologies, with SHapley Additive exPlanations (SHAP) to support interpretability. Trained and evaluated on 21,799 ECGs from the PTB-XL dataset and further validated on hospital-acquired ECG-Matrix dataset, the complete system runs in <30 s per ECG on CPU-only resources, achieving 95.51% accuracy (F1 = 0.9519) for MI detection on PTB-XL and 88.89% accuracy (F1 = 0.8862) for OMI detection on ECG-Matrix. This work showcases that legacy paper records can be reliably democratized in any part of the world, providing a scalable decision support when digital ECG export, connectivity, or high-end compute are unavailable
