AF or SVT.

[chris45558]

Today I was having a run of fast HR , so checked on my Kardia which showed Unclassified which is what I normally get with SVT , however one recording showed AFib. Then the next lot of recording showed Unclassified again.This was within a period of 45 minutes I made all the recordings.

My question is if anyone knows why it would show AFib as I've never been diagnosed with it only SVT .

Is this the start of Afib or a blip on the Kardia.

Thanks Chris

The answer lies in the EKG itself. If you can't read it, have it read by your EP, or one of Kardia's cardiologists, if that service is afforded to you.

Kardia's AI analysis (called determinations) is highly accurate, but not perfect, and yes, it can be thrown off by runs of non-afib tacycardias, incld SVT and even runs of ectopics. This is consistent with all AI algorithms, including the ones in used in your doctors office on the 16 lead. A good EP ignores them and looks at the EKG itself.

Make sure your Kardia is not near a TV or ipad or any other electricals before you start to worry. I have had unclassified if too near any of these. Move away and reads NSR. It can be unsettling to get unclassified. I have also had possible afib, wait for a bit and it is normal. If not then you might have to believe the Kardia.

My experience with Kardia is that it will say Afib if your heart rate is irregular even if you are not in Afib. I have been diagnosed with atrial tachycardia and Kardia almost always gives a determination of Afib. What I look for is the presence of p-waves before QRS complexes.

From my experience, irregular heart conditions such as multifocal atrial tachycardia, wandering atrial pacemaker, sick sinus syndrome, PAC's, and PVC's can all be misclassified by Kardia as Afib. Learning to read ECG's or ordering a Kardia clinician review are good ways to make sure Kardia's determination of Afib is actually Afib and not another condition. In the past months, I have ordered 4 reviews, all with a Kardia determination of Afib. The reviewing cardiologist came back with an assessment that is NOT Afib each time.
