I noticed in the latest app update that the Kardia has added "Bradycardia" and "Tachycardia" to its list of possible findings. Previously, a normal rhythm below 50 BPM would be called "Unclassified". I used to get those all the time. Now it says I'm bradycardic, which is correct for me.
I think this adds more weight/concern to any reading that's called "Unclassified" as they are now more likely to be flutter, bi/tri-geminy, PVCs or worse. I don't know because I can't get an "Unclassified" reading anymore. It would be interesting if anyone else can given the new application. Of course, no one is under any obligation whatsoever to share information. This is merely an update on one of our favorite AF tools. Let's hope it continues to improve.
