Large language models fail to reliably predict emergent catheterization laboratory activation from prehospital electrocardiograms.
BACKGROUND Rapid and accurate electrocardiogram (ECG) interpretation is essential for timely identification of ST-elevation myocardial infarction (STEMI) and activation of reperfusion pathways in emergency care. OBJECTIVES To evaluate the diagnostic performance of multimodal LLMs in identifying prehospital ECGs warra...
