AI Technical Summary
Existing ECG signal analysis systems lack sufficient accuracy in identifying complex arrhythmias, subtle abnormal events, and key feature points. They are also ill-suited to diverse lead settings and rhythm relationships within longer time windows, resulting in insufficient clinical applicability and accuracy, requiring extensive manual review by physicians.
A long-term ECG signal analysis method based on sparse self-attention is adopted. Through self-supervised pre-training and multi-task supervised fine-tuning stages, combined with the sparse attention mechanism, it achieves efficient processing of multi-lead configuration and input of arbitrary duration. The integration of self-supervised pre-training and multi-task supervised fine-tuning strategies enhances the model's generalization ability.
It significantly improves the applicability and reliability of automated analysis systems, reduces the workload of clinicians, and promotes the standardization of electrocardiogram interpretation and the improvement of the efficiency of cardiovascular disease diagnosis and treatment.
