Kardia

My Kardia arrived today and while it records my pulse the ECG keeps coming back as unclassified What am I doing wrong? Thanks

What is your heart rate showing ?

48 but I dont think that can be right

You will probably find that this is because Kardia do not recognise heart rates outside of 50 - 100 range.

This information is incorrect. My watch Kardia band and the mobile strip shows a range of 29 to 171.

Perhaps I should have put this more clearly. The device , as it works, will show all the rates and settle on one finally but gives an unclassified reading to anything outside the 50 -100 range. At least it does on the Kardia app on a smart phone.

I would add though that when my rate got towards 250 bpm the device kept cutting out and asking for the reading again.....not surprisingly but frustrating!

This is still incorrect.

I have been using these devices since they first came out.

I have a recording of AF at a rate of 141 and 171. I also have a recording of AF under 50.

A lot of variability depends on how the user interacts with the device.

Yes, I agree it records AF . I have it recorded at 232 AF a few days ago. When I was simply tachycardic at anything over 100 it comes back as unclassified

I also had many unclassified readings as my rate was over 100 for many days. However when I went into fast AF with a heart rate of 232 it showed as AF

Someone who knows will tell you soon, but from my recent experience, it has limitations. I also have left bundle branch block, so every reading I took came back unclassified. It wasn't able to give a reading as my heart is all over the place. It DOES work though and has its uses. I returned mine immediately for a refund. Good luck with it.

Thanks I'm not technology minded which I guess doesn't help

You could try the search box top right type in kardia or kardia reading may get some answers

If you watch Dr Guptas' video on the different ECG recorders you will see that what the Kardia is very good at is recording AF & NSR in HR 50-100. Its limitations are that some arrythmias require a reading before and after an event - these are the ones which usually come through as 'unclassified'. You are not doing anything at all wrong and should have some sort of trace.

To see it go to Journal as it will record and store every single reading - unless you delete it from your account.

Good luck. Kardia have an excellent support and the learning centre but just ask here if there is something confusing or not sure about.

mine says unclassified when my pulse is less than 60- which it is quite often at rest

Hello I have had 4 ablations and have used the Kardia since they where on the market I noticed that the unclassified readings where more noticeable when they did a software update about 2 years ago but if there's AF it won't miss that, if I get a problem I email it to my EP they know what's normal for individual patients,on my last ablation when still hooked up to 12 wire ECG machine in hospital it still said unclassified EP told me to take a trace with him watching then said that's normal for me and to use that trace as a guide, and any thing outside of that range send to him

Hope this helps good luck

You could also send it to Kardia and they will analyse for £5. As a one off it might put your mind at rest.

OK Thanks

The most likely cause is that you have not held the device correctly. You may need to practice until you are able to get a still recording. If you continue to get an unclassified recording it could mean that another rhythm apart from AF is found so you should show your doctor the unclassified recordings.

Thanks Need to practice more then Will give it a go

I had an unclassified with 106 bpm. I took a Bisprolo. My bpm came down. I've sent it off for analysis last night. I will share what they say.

Reply

Thanks That would be good

I had been sitting for half an hour when I got the unclassified. The report says sinus tachycardia. No ventricular or atrial ethics. Qrs was normal too. Best to get yourself checked over. X

I got my new Kardia yesterday; on 3 readings it registered BPM at 87, 110, and 126. It recorded AF for each reading. I am in permanent AF so that's ok. The heart beat surprises me with two in tachycardia. I find it difficult to take my pulse manually as it's all over the place. In past two weeks I have experienced fluttering for the first time. Does the onset of fluttering tend to coincide with increased incidence of tachycardia?

Ive had a kardia for 12 monrhs anything under 50 bpm is always unclassified and anything over 100 bpm when in sinus rhythm is unclassified and when you have ectopics it sometimes shows as af

Reply

My experience has been that if I'm having PACs it shows as afib. I've sent in numerous readings to their cardiologists and my report comes back saying PACs in sinus rhythm. I think sometimes when I get unclassified readings it's because there was outside interference like I was sitting too close to my pic for example.

Reply

I got a lot of unclassifieds just after my ablation when my trace looked a bit weird, also when I had a very bad infection. It was not AF but not sinus rhythm either.

My EP says to make sure you do the Kardia recording in a quiet background. Sometimes even distant rhythmic noises like a washing machine or extractor fan can confuse it. Also don't sit too near the WiFi hub or phone charger. I have had problems with these. Otherwise it mostly works well and has put a stop to those "are you sure it was AF?" questions!

Thanks I was sitting at the kitchen table near the fridge freezer so will go to another room
