A:Answer It takes a 30 second run to monitor the heart. It then labels each run as "Normal" on a green background or "Possible Atrial Fibrillation" on a dark orange background. I also had 1 run that was labeled "Unclassified" on a light orange background, so try again. Probably moved too much during run. There might be others, but I have only had these. I certainly don't want to see any with a red background (not sure there are any, but would not be surprised.)
