Researchers at the Mayo Clinic developed an artificial intelligence (AI) algorithm that can identify patients with weak heart pumps based on single-lead ECG tracings from an Apple Watch.

The researchers modified an established 12-lead algorithm for low ventricular ejection fraction (a weak heart pump) to interpret ECG signals generated from the single lead of an Apple Watch; they also developed a smartphone app that enabled study participants to submit single-lead ECGs from their Apple Watches.

Said the Mayo Clinic's Dr. Paul Friedman, "It is absolutely remarkable that AI transforms a consumer watch ECG signal into a detector of this condition, which would normally require an expensive, sophisticated imaging test, such as an echocardiogram, CT scan, or MRI."
