• Abstract summary: In clinical practice, the assignment of captured ECG recordings to incorrect patients can occur inadvertently. We propose a small and efficient neural-network based model for determining whether two ECGs originate from the same patient. Our model achieves state-of-the-art performance in gallery-probe patient identification on PTB-XL while utilizing 760x fewer parameters.

• Abstract: Electrocardiograms (ECGs) are commonly used by cardiologists to detect heart-related pathological conditions. Reliable collections of ECGs are crucial for precise diagnosis. However, in clinical practice, the assignment of captured ECG recordings to incorrect patients can occur inadvertently. In collaboration with a clinical and research facility which recognized this challenge and reached out to us, we present a study that addresses this issue. In this work, we propose a small and efficient neural-network based model for determining whether two ECGs originate from the same patient. Our model demonstrates great generalization capabilities and achieves state-of-the-art performance in gallery-probe patient identification on PTB-XL while utilizing 760x fewer parameters. Furthermore, we present a technique leveraging our model for detection of recording-assignment mistakes, showcasing its applicability in a realistic scenario. Finally, we evaluate our model on a newly collected ECG dataset specifically curated for this study, and make it public for the research community.

  We propose an inter-intra period-aware ECG representation learning approach.

Our approach demonstrates remarkable AUC performances on the BTCH dataset, textiti.e., 0.953/0.996 for paroxysmal/persistent atrial fibrillation detection.

For the soft-coding DANet, we also develop a learning framework combining self-supervised pre-training with two-stage supervised training.
