ATRIA: Adaptive Traceable ECG Reporting with Iterative Agents
For clinicians, ATRIA addresses the lack of iterative, verifiable ECG report generation, but the work is incremental as it applies existing agent-based and evidence-tracing concepts to a specific domain.
ATRIA introduces a multi-agent ECG reporting system that decouples interpretation and reporting, enabling iterative refinement and evidence tracing. It allows clinicians to verify and revise individual findings, improving trust and usability over end-to-end or single-pass systems.
Existing ECG report generation is tightly coupled -- interpretation and reporting fused end-to-end, so errors propagate without stage-level recourse -- while agent-based systems decouple tasks but remain single-pass, never revisiting earlier outputs. Clinical ECG reporting instead unfolds iteratively, requiring progressive context integration and bidirectional editing. We present \textsc{ATRIA}, a multi-agent ECG reporting system that mirrors the clinician's iterative workflow: it binds every report claim to its supporting evidence, flags statements unsupported by that evidence, incorporates additional context mid-session, and lets clinicians verify and revise individual findings rather than accept one opaque output. Because its agents use ECG analysis models already in clinical use, the underlying findings are clinically trustworthy; and as a cloud-based web service, \textsc{ATRIA} is ready for immediate deployment. We demonstrate \textsc{ATRIA} through four interaction cases, with a live demo and video available.
