Mayo Clinic’s new Apple Watch app uses AI to detect left-ventricular dysfunction

The Mayo Clinic developed a new app that transmits ECG signals from Apple Watches for AI analysis to identify heart disease.

The application transmits ECG (electrocardiograms) signals recorded in non-clinical environments seamlessly and securely to a medical center so that the AI analysis can identify left-ventricular dysfunction, a life-threatening, asymptomatic heart disease.

According to a news release, a study — for which results were presented as late-breaking clinical science during Heart Rhythm 2022 — observed 2,454 subjects from 46 states and 11 countries who downloaded the study app for their Apple Watch. The average age was 53±15 years and 56% were female.

Mayo Clinic’s app sent all previously recorded ECGs for clinician review and AI analyzed ECGs acquired within one month of a clinically ordered ECG. They were evaluated for the presence of ejection fraction ≤40% using a model adapted for single lead use.

“We have seen how artific…

FDA clears Medtronic’s AI algorithms for cardiac monitoring

Medtronic (NYSE:MDT) announced today that the FDA cleared two of its AccuRhythm AI algorithms for use with the Linq II ICM.

Fridley, Minn.-based Medtronic’s AccuRhythm AI applies artificial intelligence to heart rhythm event data collected by the Linq II insertable cardiac monitor (ICM) in an effort to improve the information provided to physicians for better diagnoses and treatments for abnormal heart rhythms, according to a news release.

The company will present data on the AccuRhythm algorithms for the Linq II ICM at Heart Rhythm 2021 this week.

Medtronic said the now-cleared, cloud-based AccuRhythm algorithms address the two most common ICM false alerts: Afib and asystole. The Afib algorithm reduced false alerts by 74.1% and preserved 99.3% of true Afib alerts, the company noted, while the “pause” algorithm for asystole reduced false pause alerts by 97.4% and preserved 100% of true pause alerts.

“Applying AccuRhythm AI …
