An ECG biomarker for sudden cardiac death discovered with deep learning.

Why it mattersCurrent SCD risk stratification relies heavily on LVEF, which misses most events and leads to unnecessary ICD implants. This ECG-based biomarker could substantially improve risk prediction, potentially guiding more targeted defibrillator therapy and reducing both undertreatment and overtreatment.
