$GTCH Perhaps one of the best known pieces of we

$GTCH Perhaps one of the best known pieces of wearable tech is Apple's Apple Watch. It was recently reported that researchers at the Mayo Clinic used an AI algorithm to interpret single-lead electrocardiogram (ECG) tracings from an Apple Watch and "effectively identified patients with a weak heart pump." Itzhak Zachi Attia, the lead AI scientist in the Department of Cardiovascular Medicine at Mayo Clinic, explained:

"Approximately 420 patients had a watch ECG recorded within 30 days of a clinically ordered echocardiogram, or ultrasound of the heart, a standard test to measure pump strength. We took advantage of those data to see whether we could identify a weak heart pump with AI analysis of the watch ECG. While our data are early, the test had an area under the curve of 0.88, meaning it is as good as or slightly better than a medical treadmill test. AI analysis of the watch ECG is a powerful test to identify a weak heart pump."
