A lightweight and robust method for electrocardiogram anomaly detection and localization using multi-scale masked autoencoder
Fig 3
Examples of anomaly localization on the PTB-XL dataset across different types of ECG abnormalities.
Ground truth regions, annotated by cardiologists, are highlighted with red boxes on the ECG signals, while the corresponding anomaly localization results based on the point-level anomaly score (defined in 5) of the proposed method are shown below. Detailed descriptions are provided in S1 Appendix.
