ECG-Reasoning-Benchmark (PTB-XL) - Diagnosis Given Reference Reasoning: leaderboard
Metric: Diagnosis accuracy (%) at the final decision step when the complete ground-truth reasoning history is supplied in the prompt (GT-RDA), on the 3,076 PTB-XL samples, multi-turn ECG reasoning chains for 17 core diagnoses (balanced positive and negative cases), 12-lead ECGs given as plotted images (OpenTSLM as a 100 Hz time series), temperature 0; each step's answer is checked for semantic agreement with the ground truth by a Gemini-3-Flash judge; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 19 models tracked.
