Research Paper Overview
ECG-aBcDe: Overcoming Model Dependence, Encoding ECG into a Universal Language for Any LLM
Summary
This paper introduces ECG-aBcDe, a novel ECG encoding method that converts ECG signals into a universal language interpretable by any large language model (LLM). It addresses limitations of current ECG analysis methods by enabling transferability across LLMs without architectural changes, explicitly representing time-scale information, and enhancing interpretability through bidirectional convertibility and attention heatmaps. ECG-aBcDe achieves competitive performance on standard metrics and significantly improves BLEU-4 scores in both in-dataset and cross-dataset evaluations, demonstrating feasibility for a new paradigm in ECG and LLM integration.
