New benchmark reveals LLMs struggle with ECG clinical reasoning

Researchers have introduced the ECG-Reasoning-Benchmark, a new evaluation framework designed to assess the clinical reasoning capabilities of multimodal large language models (MLLMs) in interpreting electrocardiograms (ECGs). The benchmark, comprising over 6,400 samples for 17 core ECG diagnoses, revealed that current MLLMs struggle with multi-step logical deduction and grounding their reasoning to visual ECG evidence. While models can retrieve diagnostic criteria, they often fail to maintain a complete reasoning chain, indicating a limitation in their visual grounding abilities and a need for more robust, reasoning-centric medical AI. AI

IMPACT Highlights a critical gap in current MLLMs' ability to perform genuine clinical reasoning, necessitating advancements in visual grounding for medical AI applications.
