AI tracking of ECG changes in adults born with heart defects
Machine Learning Based Analysis of Longitudinal Changes in the Congenital Heart Disease Electrocardiogram
This project uses artificial intelligence to spot gradual changes in ECGs of adults born with heart defects so worsening heart problems can be caught earlier.

What this research studies
You would contribute routine ECG recordings that the team will analyze over time using machine learning and time-series methods to find subtle changes in heart electrical signals. The researchers will look at waveforms, conduction intervals, and other ECG features and track how they change by age, sex, race, and ethnicity in adults with congenital heart disease. The goal is to identify ECG-based biomarkers that signal early chamber dysfunction or fibrosis before symptoms or expensive imaging show problems. If patterns emerge, the approach could allow remote transfer of ECGs for centralized analysis to help guide when interventions are needed.
Who could benefit from this research
Good fit: Adults (21+) born with congenital heart defects who can share past ECGs and agree to ongoing ECG monitoring or remote ECG transfer would be ideal candidates.
Not a fit: People without congenital heart disease, children under 21, or those who cannot provide serial ECG data are unlikely to benefit from this work.
Why it matters
Potential benefit: If successful, this could give adults with congenital heart defects earlier, clearer warnings of worsening heart function so interventions can be timed to prevent complications and reduce unnecessary imaging.
How similar studies have performed: AI has already shown promise detecting several heart problems from single ECGs, but using longitudinal, time-series AI specifically for adult congenital heart disease is largely new.
