- Diagnosing as Cardiologists Do: ECG Agents with Doctor-Grounded Priors for Clinical Reasoning Across Diseases and Populations2026 · arXiv preprint
LuminaECG treats ECG interpretation the way cardiologists read it: as measurement-based visual reading. A general 2B-parameter vision-language model is fine-tuned with low-rank adapters to link measurement primitives to diagnostic reasoning, without changing its architecture.
