Kardia came back as AFib with rapid ventricular response ??

[chris45558]

Yesterday I posted I had a run of fast HR around 190It went on for around 20 minutes but not continual. A couple of times I stopped it by blowing it the srynge or simply stood up straight. My normal tripper is good.

I took a few recordings and they came back as unclassified which is normal for me and as Kardia will never come back and say SVT, however I've shown these to a cardiologist and said SVT, so I've always taken these as SVT.

I had an unsuccessful ablation for SVT a couple of years ago due to being too close to the AV node.

Yesterday one recording came back as Afib( this has never happened before) and I've only been diagnosed with SVT. I took a few more recordings straight after the Afib one and all came back as unclassified, again I took this as SVT.

I sent the Afib recording off and came back today as AFib with rapid ventricular response..no idea what the rapid ventricular response means???

My question is, is this the start of Afib or could it simply be a one off??

I will call my GP Monday as I was discharged by the hospital sometime ago.

I'm 57 and about to start a new job next week so really could do without the stress.

Thanks Chris

Who analyzed the ekg and told you it was afib? If it was a trusted ep, then that's what it probably was. You can have SVT and afib together, I did. Afib "with rapid ventricular response" simply means afib with a fast heart rate. This is the most common type of afib, although some have afib with a normal heart rate.

I found the blowing into the syringe conversion worked frequently with SVT (by itself or as part of the "modified valalva manuever", but never worked with afib. This is also supported by study data.

Hi Jim it was analyzed by the Kardia team. Not sure who does it there.I took another recording within a minute and nothing about AFib on that one.

Hi Jim it was analyzed by the Kardia team

That doesn't necessarily mean an ep lookd at it. At least in the US, you can have it analyzed by a "tech" or a "cardiologist" and not sure the cardiologist is an ep. Certainly better than the AI interpretation, but given your history, I would confirm with a trusted ep, before drawing the conclusion that the tracing was afib.

When you had SVT and AFib together and the SVT stopped after the syringe did it still show AFib on a Kardia?

[mjames1 in reply to chris45558]

When I said, I had "afib and SVT together", I meant I had both conditions, but never at the same time. I pretty much knew the difference by the Kardia tracing as well as my heart rate, so when I went into SVT, I tried the "modified valsalva manuever", with the syringe if around. I tried the same with afib, the modified valsalva never worked. This is consistent with some studies I read.

Ah right sorry I misunderstood but that makes sense now

Whoa, what's the syringe thing? Been on this forum for a year or so and not heard of it before. Am I missing something?

[chris45558 in reply to 50568789]

You can use a syringe for valsalva manuever when in SVT. He blow into it for 15 seconds and it can get you out of SVT.It's always worked for me

Never worked for me when in AF I am afraid

Putting your face in ice cold water is another method

[mjames1 in reply to ian16527]

The modified Valsalva Maneuver (raising your legs and blowing into a syringe) is not meant for atrial fibrillation just SVT.

Thats good to know, even though they have tried twice in A&E to do the syringe method.👍

Google "modified Valsalva manuever for SVT".

What happens is the unwanted wild rogue signal in the Atrium bump into the AV node and if this happens more than want is wanted you'll get a fast Ventricular response and will become symptomatic. People who usually have silent Afib and dont feel get might not get those Ventricular reponses and they dont hit the AV node. If the hit the AV node your ventricles will contract . I get regular Unclassified and I just get a handful of extra beats and don't matter if they are PACs or PVC. For me I find Unclassified is just short of the Afib threshold
