Hi I'm thinking about taking the plunge and getting either the 1 or 6 lead kardia device.
My irregular heart rhythms tend to be bought on just after excericse when the heart rate exceeds 115bpm ( according to my watch).
i would like to know from your personal experience and usage is the kardia device reliable in measuring an ecg immediately after excericse or does it too suffer from the effects of muscular noise which cause artifacts thus dodgy ecg readings?
many thanks
Hi
I have Kardia 6L which I now use sparingly as part of my PAF surveillance regime, usually when something feels off; which thankfully is not too often.
When I first purchased the device I did a little experimentation and collected some traces immediately after exercise. My HR was still high as i recovered - HR over 100bpm - no surprise, it's determination was tachycardia. When it dropped below 100bpm, it reported NSR. The traces were ok, pretty clean. My PAF does not appear to be triggered by exercise anyway.
The only time I have interference is if my skin is too dry or my garments have some static. Take it off or earth myself, and its fine.
thank you that's very interesting so it registered something as simple as a high heart rate post excericse as an issue.
The device just captures and records an ECG then makes a rhythm determination. It does not know if you have just ran 5k or have been sat on the couch for a few hours.
l am unable to help with Kardia but maybe someone will come along and help you with that.
I am not medically trained, but you say your irregular heart rhythms happen after excercise, when your heart rate goes over 115 bpm. For me, personally, that would ring alarm bells that l was putting too much strain on my heart. I get AF from over exertion so, reluctantly, have had to slow down. I think it is essential to listen to your body and not push yourself over the limits, especially if it is causing an AF episode.
Perhaps you have already sought advice from your Cardiologist, but if not, l would ask if this is ok for you?
I have a 6 lead kardia and found it useful and easy to use. Interesting that the first thing my cardiologist wanted to see before my ablation was the kardia readings so he could assess what had been happening.
I was introduced to having a Kardia (and smart phone to use it) by the private EP we saw after the lowest dose of Bisoprolol proved too much for me to take daily. After I’d sent him the reading of my heart in AF, he sent a prescription for Flecainide to my surgery for me. At first I took it as a PiP but now, taken regularly, it has virtually put an end to episodes and I’ve even managed to reduce the first dose of the day which I am about to take now!
Hi, May I ask what dosage flecanide you take? I was on 25 mg twice per day until I started having such horrible side effects. I now take metoprolol. I wish Flecanide had worked. It took away all my SVT symptoms but made me soooooo dizzy and weak. Thanks!
I've not had any issues with interferance recording from my 6L Kardia providing I'm sitting still when it's being done. It's satisfactorily proved my AF to my GP without the need to wait for a Holter monitor etc.
My experience of three different devices suggest that all fingertip devices suffer from noise, and that can easily be excessive and lead to a poor reading. Sweat can also impact the ability to take a reading. Any look at the Kardia "unsmoothed" output (which the software allows) would make you wonder how the software sorts out much at all. But it does - and does it well. It's a good product, but there is always the pressure to pay a monthly fee for "Advanced Determinations".
It's for the latter reason that I have found myself preferring different products. I have three but these days use just the one, most often (yes, I like gadgets, and I do also sometimes get to review them freely for a big online seller). They are the Contec PM20 (the same as the Emay 6L), the Wellue 24-hour ECG Monitor and the Wellue Touch Screen ECG Monitor. All are very reliable and accurate and offer an AI analysis that comes free with the device, so no monthly charges. I tend to use the Contec most days as it seems to be happier with my bundle block issue. The Wellue (both of them) allow ECG electrode patches to be used, thus circumventing any "noise" and they can, I suppose be used during exercise.
