For the first time, Yale researchers have been able to diagnose structural heart disease using the simple electrocardiogram (ECG) sensors found in a smartwatch. Their findings will be presented this week at the American Heart Association’s Scientific Sessions 2025.
While wearable devices are increasingly used to diagnose and monitor heart diseases that affect the heartbeat, such as arrhythmia or atrial fibrillation, their single-lead ECG design has so far limited their ability to diagnose physical defects in the heart. However, with the help of artificial intelligence (AI) algorithms, a group of 600 patients in a real-world hospital setting could be diagnosed with high accuracy from just a 30-second smartwatch read.
“On its own, a single-lead ECG is limited; it...
