Full Summary
Atrial fibrillation (AF) is a prevalent heart condition that increases the risk of serious health issues. Recent advancements in ECG (electrocardiogram) foundation models have shown promise for automated AF detection, but their effectiveness has been difficult to compare due to varying methodologies in previous studies.
FOUND-AF was developed as a standardized benchmarking framework to assess nine ECG models, including HuBERT-ECG and ECGFounder, across four diverse datasets. The evaluation employed consistent preprocessing, a fixed XGBoost classifier, and rigorous validation techniques.
Results indicated that the ECGFounder model consistently outperformed others, achieving a strong balance between accuracy, model size, and inference time. This framework not only aids in selecting effective ECG models but also highlights the potential of compact, pretrained encoders for reliable AF detection in varied clinical settings.
