EP study after ablation

After my His bundle/AV node ablation, next day I had an EP study.  It showed that they can induced the SVT.  Then it followed with a heaps of EP studies.  One of the cardio said, it is not normal.  He said, "normally, after AV node ablation, it is unable to induce SVT".  Anyone knows or have an idea what is going on?  Thanks

Hi PikaPika88,

I don't know what is going on, but I'm wondering if you have thought about a second opinion.  I'm not sure why you didn't have the EP study before your ablation.  But, if I understand correctly, you had an AV node ablation and THEN an EP study.  At that time, the doctor was able to induce SVT.  Then, you had more EP studies where they were not able to induce SVT.  Is that right?

What are your current symptoms?  What is "not normal"?  Do you still have SVT?  Sorry for so many questions...

Hi Connie,

Thanks for answering my post.

I had the EP study before the AV node ablation.  

Yes, I had an AV node ablation and then an EP study following day .  At that time, the doctor was able to induce SVT.  Then, I had more EP studies.  They were able to induce SVT.  

One of the cardio said, "normally, after the AV node ablation, it should not be able to induce SVT".  

Current symptoms are very confused.  Do I still have SVT?  Pacemaker will pace out all of the unwanted rhythms.

hiya i have svt and still have svt after my ablation 4 months ago,
the doctors too told me after the ablation the svt would no longer be a problem but i'm back on flecanide as my svt has returned,

i have found that many people still suffer with svt after the ablation and many need a second op,
if the 2nd op is not working they normally opt for a pace-maker. are you still having svt attacks?

i have to say my svt after ablation were fairly mild but have become more severe now than what they were before my op, but the doctors still maintain it's highly unusual but there are many people out there that have had the same thing happen, i think they are just in denial that the op doesn't always work as well as they hoped.

if youre not happy go back to your cardiologist, or get a second opinion. good good luck hey you may be lucky your svt may well not return.

Good Morning Pika - I'm just thinking about this and guessing so don't think I have the right answer.

They ablated your AV node (the gateway between the upper and lower chambers of your heart) then put in the pacemaker to keep the lower part (ventricles) pumping well. Then they said you still have SVT. SVT has to do with the upper chamber of the heart, the atria. So could the upper part still be beating erratically or too fast? The fast signals wouldn't make it to the ventricles because of your ablation but the upper part could still be acting badly. At least this is how I'm picturing it in my mind.

Thanks for the post.

After the ablation, I didn't have any more palpitation.  Considering a successful ablation for 20 years.  Now, he said I got AF and AT.  When I went to see a second opinion cardio, I handed all my info for him.  He told me that it is not normal after the av node ablation, next day can induce SVT?

I may be lucky that I didn't have SVT anymore but it comes the A-Fib and A-Tachy!  I used have RBBB, now also got LBBB due to the pacemaker pacing.  I don't know you still would like to be me or not as lucky or not lucky?

3 years before the av node ablation, they implanted a pacemaker for my svt but not successful.  My heart rate over rided it.

Thanks for the post.

I think you're right.  Like AF, after the av node ablation, AF still occur in the Atrial.  It will Fib to dead.  It wouldn't affect the ventricle.  Would SVT the same?  It will Tachy in the Atrial to dead?   I hope some one can give us the answer!   Is AF same as SVT behaviour?  

But my pathway manifest, it connected from Atrial to ventricle during my heart block.  It replaces the AV node.  I didn't feel any palpitation during 20 years.  All the time the pathway works essentially.  My pacemaker sat there for insurance only.  Now AF, he said it increases my ventricle rate.  Once he said, due to my previously av node ablation so it only have a short bouts, not concern.  Then why I didn't have svt anymore after the ablation?  They said they can induce it?   I wonder they wrote something wrong there or the doctor even more confuse than me?

I don't know are there any more cases out here like mine?  I hope they can come in and share their experiences.

SVT is a general term for various tachycardias affecting the upper part of the heart. It could be PSVT (the heart rate jumps up without warning and reverts back to normal just as quickly after a period of time), MAT,  a-flutter and a-fib. There may be a few others but I can't think of them right now.

I know you've been getting so many different stories from your doctors and some of them haven't always been patient or polite about it. I'm not sure your heart will ever act perfectly normal but it would be helpful to at least know what's happening in there. At least it helps me to understand even if they can't fix it.
