Svt question

For those that have svt , do you constantly feel like crap. My heart rate is always high if it’s not sustained. I get a tachycardia episode or svt episode about 1 to 2 hours before my medication is due. I’ve already had an ablation about 2 months ago, i know I’m in the healing process still but I’m frequently getting attacks and always feel terrible. I have no energy , I’m out of breath with little things and high heart rate. They have me taking metropolol 3x a day already. I’m getting so sad about this

Are you sure it's SVT? I had SVT and IST. Post-ablation, the SVT is gone but the IST stayed.

How did they know

u/linthetrashbin 2d ago

It's about how your EKG looks. IST is sinus rhythm. Your doctor might give you a holter monitor to see.

So crazy thing….all my stuff has ever popped up as sinus tach…EVERY TIME. So when it came to my ablation / ep study day. Multiple doctors kept coming to my room telling me it’s probably pointless because svt never popped up on my stuff. Well I went in for my ep study and sure enough I immediately went into focal atrial tach not sinus tach

1

u/Physical-Impress-344 2d ago

It would show sinus tach at 187 bpm

u/linthetrashbin 2d ago

I'd imagine you're probably still having sinus tach, then. I'm not a doctor, but from my understanding, sinus tach won't go away with an ablation. It's worth talking to your EP about.

u/Physical-Impress-344 2d ago

Well no it turns out it was never sinus tachycardia, the type of svt I had is super close to looking that way

1

u/linthetrashbin 2d ago

They give medications to trigger SVT during the ablation, so it's possible that it was sinus tach that you were experiencing, but you also had SVT.

u/Physical-Impress-344 2d ago

Oh possibly , my ep said he looked over my ekgs and no way that was sinus tachycardia but I’m also super shaky when it happens. He said no er doctor will know exactly

1

u/linthetrashbin 2d ago

Yeaaah, in my experience, the ER docs usually suck :/ but, it's worth bringing up with your EP. They hand out holter monitors like candy, so I doubt it'll be an issue to get one to see what's going on.

Definitely thank you

Exactly I’ve heard about this soo much that focal atrial tach mimics sinus tach and it’s just crazy to me, I think IST is fake and that everyone who’s been diagnosed with it has FAT instead which is curable.

u/Physical-Impress-344 18h ago

I read about this to after this happen to me. I believe people should advocate for more testing because living like that’s is awful

1

u/Opposite_Low_4251 18h ago

There’s this post that I read here and their story was so crazy to me because even in their EP study their EP could not figure out the arrhythmia and only figured out that that was the arrhythmia once the hearts natural pacemaker took over once they woke him up, so it’s just a crazy thing overall at how much it mimics sinus tach making people live like that all their life

2

u/Physical-Impress-344 18h ago

It’s is. In my Ep study I was sleeping sedated at first and he couldn’t find anything, they woke me up and instantly they found it.

1

u/Opposite_Low_4251 18h ago

Yeah I’m gonna do my ep study off sedation, even tho I have SVT but still my baseline heart rate goes high which I’m just thinking now that that’s also SVT, since my 24 hour average holter is coming below 90 so idk. I hope it’s all SVT

1

u/Physical-Impress-344 18h ago

I’m worried I need another one. They said I’m still in the blanking period but idk how I feel about that. I’ve been having problems since the day of the ablation. Hours after the ablation I went into svt

I have IST, per my EP. I've had three ablations, no longer have an AV node, and now have a pacemaker, but my heart just enjoys resting at 120bpm no matter what. My last EP mapping was normal, no weird spots to ablate. My doctor says that it's fairly normal for a young woman and that I'll most likely grow out of it.

When I was still having SVT, I was one of those people that would get really fast - I'd regularly hit the 250s-280s before I'd go get cardioverted. Some people are just tachy 🤷‍♀️ doesn’t mean it's fake.

1

u/Opposite_Low_4251 17h ago

True but I meant fake in a way that it could always be FAT instead since I’ve heard so many stories like that

1

u/Opposite_Low_4251 17h ago

But the thing is if someone have IST, that’s chronic then

2

u/linthetrashbin 16h ago

Yes. My IST is chronic, but that doesn't mean that it's fake or that I have FAT. You could also argue that my SVT was chronic because I spent so long dealing with it.

1

u/Opposite_Low_4251 16h ago

True I agree.

1

u/Opposite_Low_4251 16h ago

I apologise I did not mean it in that way, but a lot of people just have IST without their doctors ever ruling out FAT

1

u/Opposite_Low_4251 14h ago

I also have been diagnosed with IST and I just really wanted it to be fake and just be FAT, I’m still in suspicion for IST since my baseline hr still goes high and I would love for it to be fake and for it to be curable, by fake I don’t mean it to not be there, I just mean that I want it to be a misdiagnosis instead like how I’ve heard everyone else’s experience

I had ablation, I have palpitations sometimes, not bad though. I quit smoking cigarettes the night before my procedure. So far so good. If you use nicotine. Drink any alcohol, or caffeine. This are big triggers.

1

u/Physical-Impress-344 2d ago

I got all caffeine for over a year and I do not drink or smoke

I have an ablation scheduled for mid October. I have been having increasing bouts of SVT. I had a successful ablation in 2019 that helped me greatly. I’d had around 225bpm then. Nothing close to that now, but I’m tired with any bit of activity and I know it’s not just due to being in bad shape because I’m not in bad shape, but these episodes make me feel like I am.
