@mjohns For what it’s worth, I’ve found the KardiaMobile to be super helpful in detecting paroxysmal afib especially during the day as the Apple Watch or Fitbit inspire 3 will only recognize the arrhythmia if it persists for 10 min while you are still. So during the day, it was often missed- only registered when I was asleep. Since I’m pretty symptomatic the Kardia picks up short runs best for me during the day. Good luck!
