Around one-third of the participants who received irregular heartbeat notifications and followed through with ECG monitoring were accurately identified as suffering AF. While the device was good at identifying users who had AF, two-thirds of the cases it identified were false alerts. This creates unnecessary anxiety and activation of healthcare providers. More follow-up studies are likely; interested clients should monitor.
