Hello @elliott, I combined your post into the discussion titled "Medical devices to monitor heart rhythm (i.e., Alivecor, KardiaMobile)" - https://connect.mayoclinic.org/discussion/kardiamobile/.

Here, you can meet members @thisnthat, @afibguy, @janet23, and @balmich have all posted in this discussion about using an Apple Watch or the Kardia devices. They may be able to share their own experiences with why there are differences in the capabilities of both.

@elliott, you mentioned your watch was what first indicated that you should go be seen and that it led to your diagnosis. Did your cardiologist have a recommendation on which device to use and if so, when to use it?
