LLM-based staged extraction framework localized PVC origin as left versus right from 12-lead ECG images with discrimination comparable to a CNN baseline while providing a traceable stepwise diagnostic process.
Researchers tested whether large language models could interpret 12-lead ECG images to distinguish left- versus right-sided origins of premature ventricular contractions in 157 patients who had undergone successful catheter ablation. By August 2026 they reported a staged extraction framework that produced a traceable stepwise process and a continuous score whose discrimination was numerically similar to a CNN baseline.
