Well, I've never in the 8 or so A-Fib flair-ups I had, did I have a perfectly normal (i.e. around 60-75) RHR (resting heart rate), so should in the unlikely event I ever have yet another A-Fib flair-up, I'll know right away with my 235, and will take appropriate & immediate action.
Aufgrblassen Huh? Was that supposed to be an explanation why you would want such a feature, when all we were doing is tell you we've never come across such a feature in the FR235 as long-time users? If you want to make a feature request or suggestion directly to Garmin, please do so. It's really of no use telling us here why you may want it, or how important it would be to you; your fellow forum members, Garmin customers and device users aren't feature implementers.
