Wearable ECG AI for AF Risk
This module highlights the significant association between the AI-ECG age gap and Atrial Fibrillation. The PROPHECG-Age Single model provides a continuous, personalized measure of AF propensity and disease burden, enabling proactive cardiovascular monitoring beyond traditional episodic detection.

Higher Odds of AF per Year of AI-ECG Age Gap (pooled adjusted)
Each 1-year increase in AI-ECG age gap was associated with 3% higher odds of prevalent atrial fibrillation (pooled adjusted OR 1.03, 95% CI 1.01–1.04) and a 0.80 percentage-point increase in AF burden. This supports wearable-based AI-ECG age as a potential digital biomarker for proactive cardiovascular monitoring.
