I have looked at the app that was recommended for this and it looks like you have to put your fingers on a small pad?? I'm not sure I'd ever get it set up in time! I have some short runs that I can't tell if they are PVCs or a-fib or what but it looked like the recording wasn't automatic. I'm on Android, but would be willing to change if it would give my cardiologist some more information! Can you give any specifics??
