CardioFM: A Multimodal Foundation Model for Joint ECG and PPG Representation Learning

2026-05-11

Abstract excerpt

<title>Abstract</title> <p> Electrocardiography (ECG) and photoplethysmography (PPG) arise from the same heartbeat and are routinely co-acquired at every monitored bedside, yet no foundation model jointly encodes both modalities. Existing approaches are either ECG-specific, PPG-specific, or domain-agnostic, and none captures the cross-modal physiological coupling between cardiac electrical activity and periphera...
