FAQ: AI Smartwatch Detection of Structural Heart Disease
TL;DR
This AI-powered smartwatch ECG tool provides early detection of structural heart disease, giving users a health monitoring advantage over traditional screening methods.
The AI algorithm analyzes single-lead ECG data from smartwatch sensors to detect structural heart conditions with 88% accuracy in real-world testing.
This technology makes heart disease screening more accessible worldwide, potentially saving lives through early detection using devices people already own.
Your everyday smartwatch can now detect hidden structural heart problems like weakened pumping ability using AI analysis of ECG data.

An AI algorithm paired with single-lead ECG sensors on smartwatches accurately diagnosed structural heart diseases including weakened pumping ability, damaged valves, and thickened heart muscle in adults.
This technology could make screening for structural heart disease easier and more accessible since millions of people already wear smartwatches, unlike traditional echocardiograms that require special equipment and aren't widely available for routine screening.
Researchers developed an AI algorithm using over 266,000 12-lead ECG recordings from more than 110,000 adults, then adapted it to work with single-lead ECGs similar to those obtained from smartwatch sensors, accounting for real-world signal interference.
The algorithm can identify weakened pumping ability, damaged valves, and thickened heart muscle.
The model was externally validated using data from community hospitals and a population-based study from Brazil, then prospectively tested on 600 participants who underwent 30-second, single-lead ECGs using a smartwatch in a real-world setting.
The study was conducted by researchers including Dr. Arya Aminorroaya from Yale New Haven Hospital and the Cardiovascular Data Science Lab at Yale School of Medicine, and will be presented at the American Heart Association's Scientific Sessions 2025 in New Orleans.
This is a research abstract presented at a scientific meeting and the findings are considered preliminary until published as full manuscripts in a peer-reviewed scientific journal.
Structural heart diseases are usually found with echocardiograms, which require special equipment and aren't widely available for routine screening, while smartwatches are already worn by millions of people and could provide more accessible screening.
The system uses the single-lead ECG captured by the electrical heart sensor on the back and digital crown of a smartwatch.
It could help find hidden structural heart diseases earlier, before they progress to serious complications or cardiac events, making screening more accessible to everyone using devices they wear daily.
