Does anyone have problems with your Kardia giving unclassified responses? My normal heart rate is less than 50 bpm and I read somewhere that you need at least 50 for it to register. I usually have to run in place or do jumping jacks before taking my readings.
Also, sometimes I get unclassified then try again and get wild spikes on the readings. It may say possible Afib, then I try again and it reads normal. I’ll verify against my blood pressure machine and it shows normal rhythm too. Then i’ll go back to Kardia and it show normal again. Kinda freaks me out when it varies from unclassified to Afib to normal.
Anyone else experience this on your Kardia? Cause?

I get a number of unclassified readings on my Kardia device as well. Anytime my pulse is under 50 and often when I see what looks like premature beats. Sometimes it shows a lot of erratic lines until it settles down into a rhythm too. But it seems to do a great job of confirming Possible Atrial Fibrilation whenever I am feeling AFIB. Sometimes the report can look totally normal to me and be pulse over 50 and it still can say Unclassified. If I repeat the reading it sometimes will say Normal. I don’t think I’ve ever had it say Possible Atrial Fibrillation and surprise me. ... I think it’s a wonderful little device.

I ,too, had issues with my normal low pulse rate,and PACs as well, that regularly confused my Kardia so, much as I appreciated the help it provided for the last year, I had Santa deliver a new Apple Watch 4, and no longer have any issues. I have still used the Kardia to see if they agree...and they often do not. kardia reads unclassified and an occasional possible afib, when Apple Watch 4 says normal synus rhythm. I had my EP read the kardia ECGs and was told they were wrong, I was in normal synus rhythm. So I am happy I have made the switch, but will always be glad I had the Kardia when I was so often in crisis and going from one med to another. when I really KNEW it was aflutter or afib...kardia agreed...and when I would go back into rhythm..it generally agreed. It has been all the iffy stuff since we found a good rhythm med for me and I believe the Apple is superior. Pat

I experience many unclassified readings and sadly few normal readings even though my pulse rate is almost always above 50bpm. Possible AFIB is spot on as I know when I'm in AFIB. There was a period of time over a year ago where the EKG waveform experienced many aberrations and spikes. That problem is very infrequent since I use a repeatable setup and location when I take my readings. I still find the device very useful.

Well, that’s comforting to read; that others too get unclassified and false AFib readings with Kardia. Don’t get me wrong - I still like it. It just is unsettling until I take more readings to finally get a normal reading after ones that say possible AFib. I don’t have the kind of AFib that goes in and out - Your either pregnant or not. So when the normal reading comes out I’m good with it.
I believe sometimes the unclassifieds and wild spikes can be poor connections on the finger pads or a low battery. I hope they make a model that shows the battery level in the future.
Keep on ticking everyone!!

Some people get poor readings because the default reading is set to 30 seconds. You can increase that to 60 seconds, even 120 seconds, and that can increase the accuracy of the reading.
If you get messages about poor signals, that may be an indication of a weak battery that needs to be replaced.
Sometimes there is not good contact between the fingers and the pads, so washing your hands can improve the contact.
P.S. Why are some of you having heart rates below 50? That is concerning. Is it that you are on a beta blocker or calcium channel blocker that has depressed your heart rate? I am trying to finish up the videos with Dr. Prystowsky that may shed some light on things you may want to discuss with your doctor.

In my case I’ve historically had low heart rates. I’ve been pretty active in sports growing up and today I’m still an avid tennis player at 68. I’ve had a few cardiologist over the years and all of them agreed that it’s not a concern in my case. In fact they say it’s good. I’m typically below 50pbm after I wake up in the mornings and that’s when I do my Kardia. After I’m up and walk around the bpm goes up to mid to high 60s.

Unclassified is a common reading. I've found that a few things can be involved: 1) pulse under 50; 2) poor contact (I now dampen my fingers); 3) Electrical interferance. Sometimes it will tell you that there is electrical interferance, but sometimes not. I have found that I have to take readings from my bedroom--away from the fridge, router, TV etc. That usually does the trick. As far as HR below 50, I also used to have to run in place to get my pulse up but turns out it was sick sinus syndrome and I now have a pacemaker. I had always had a low resting heart rate but it kept getting a bit lower over the years (and finally I was getting pauses). Just something to watch with your EP as it can sneak up on you.
