- 基于U-net架构，从少导联数据重建12导联心电图
- 揭示了各导联间的信息冗余与相关性，识别关键导联
- 适合便携设备、远程医疗和个性化心脏诊断场景
本研究提出一种基于U-net架构的深度学习模型，用于从减少的导联配置中重建12导联心电图（ECG）。模型在公开数据集上训练，能够量化每个导联的信息含量及其导联间的相互关系。结果表明，该方法可有效识别关键导联，减少冗余，为临床诊断中导联选择优化提供依据，尤其适用于无法获取完整12导联的心电图场景。研究还深化了对心电信号生理机制及传播规律的理解，为远程医疗、便携式心电设备及个性化心血管诊断的发展奠定基础。
原文摘要 · Abstract (English)
This study introduces a deep learning model based on the U-net architecture to reconstruct missing leads in electrocardiograms (ECGs). The model was trained to reconstruct 12-lead ECG data from reduced lead configurations using publicly available datasets. The results highlight the ability of the model to quantify the information content of each ECG lead and its inter-lead correlations. This has significant implications for optimizing lead selection in diagnostic scenarios, particularly in settings where complete 12-lead ECGs are impractical. In addition, the study provides insights into the physiological underpinnings of ECG signals and their propagation. The findings pave the way for advances in telemedicine, portable ECG devices, and personalized cardiac diagnostics by reducing redundancy and improving signal interpretation.
