Stanford Medicine Reports Results of Apple Heart Study for Detecting Atrial Fibrillation

Shots:

  • The Apple Heart Study was started in Nov’2017 in conjunction with the release of Apple’s fourth-generation smartwatch and watchOS 4. The study evaluated 419,297 participants and demonstrated that 0.5% of them received irregular heart rhythm notifications, published in NEJM
  • Those who were flagged for an irregular pulse received follow-up care via the ECG patch. During ECG patch monitoring, participants’ Apple Watches continued to monitor pulse irregularities. If a participant had an irregular pulse detected, 84% of the time it was confirmed to be AF on the simultaneous ECG patch
  • The study results demonstrated that the algorithm in the Apple Watch can successfully detect AF. Among participants with a notified irregular pulse, the positive predictive value was 0.84 for observing AF on the ECG simultaneously with a subsequent irregular pulse notification and 0.71 for observing AF on the ECG simultaneously with a subsequent irregular tachogram
