AI models struggle with ECG classification; new methods aim for better accuracy and interpretability · 2…

Two new research papers explore the limitations of current AI methods in classifying electrocardiograms (ECGs) and propose novel approaches to improve accuracy and interpretability. The first paper introduces RecursiveECG, an LLM-based agent designed to recursively refine ECG classifiers by analyzing specific failures and using objective ECG evidence. This framework achieved a 10.0% average relative improvement across datasets. The second paper evaluates existing Explainable AI (XAI) methods for ECG classification, revealing that many methods, particularly those transferred from computer vision, fail to align with clinical guidelines and often focus on signal amplitude rather than diagnostic relevance. This study highlights the need for global, domain-grounded evaluation to uncover systematic explanation failures. AI

IMPACT These studies highlight critical gaps in current AI evaluation for medical applications, pushing for more robust and clinically aligned methods in diagnostic AI.
