*The WatchPAT® is not intended to be used as a diagnostic device for any cardiac arrhythmia and is not intended to replace traditional methods of diagnosis for cardiac arrhythmias. In cases where the longest AFib episode detected is shorter than 60 seconds, review of the PAT® signal for an irregularly irregular rhythm in the location of the episode is recommended. The WatchPAT® may not detect short AFib episodes (<60 seconds).
