Researchers have developed MorphologyFM, a novel foundation model designed to learn representations from electrocardiogram (ECG) and pulse oximetry (SpO2) waveforms. Unlike previous methods that focus on reconstruction or forecasting, MorphologyFM explicitly preserves the clinically significant morphological structure of these physiological signals. The model utilizes a morphology-aware self-supervised learning objective, combining guided masking, cross-modal learning, and contrastive latent alignment. Evaluations on various prediction tasks, including arrhythmia and hypoxemia prediction, show MorphologyFM outperforms existing self-supervised learning techniques and demonstrates that joint modeling of ECG and SpO2 yields more transferable representations.
