r/SVTHeart

I was supposed to have one two years ago and ended up pregnant (with twins!). Had another episode of SVT this last February.

Finally seeing my EP today. And we will be scheduling the ablation.

What do I need to ask? I’m a floor nurse and a clinical instructor, and have seven kids (ages 1-11).

I’m precepting a student this summer and then go straight into the semester, so I’d really like to not be off work long…especially since my preceptor is competent and will be doing most of the work under my supervision, but as we all know, anything can happen.

What do I need to ask about recovery? Time off? Risks related to other health issues? Hospital stay?

Anything you wish you’d known?

Do you guys ever get those mild "blips" where you get the sensation of "Oh I'm about to have SVT episode" where it physically feels like your heart is going to start having an SVT episode, only it lasts a second and then the sensation stops?

I'm a year post-ablation for SVT I had for 5 years. I ocassionally get these but haven't had a full SVT episode since. Just curious if you guys experience this, and if so how you cope mentally. It freaks me the hell out and I go into complete obsession, convincing myself "the ablation didn't work and my heart is failing!!!" despite it never amounting to anything.

Just looking for experiences here.

Thank you all!

Hey guys, I was wondering if anyone else had this experience, but my doctor told me that my monitor results were benign and normal even though I still had some short burst of SVT

I take a therapeutic dose of a beta blocker so how is that a normal finding? I feel like it would be normal in benign. If I wasn’t on meds, I’m just really concerned and confused.

2 days out from ablation and I’m spiraling. My svt was found but it wasn’t ablated completely bc it was too close to the av node. I also apparently went into afib several times and needdd to be cardioverted which they told me sometimes happens due to the electricity and drugs they give you to try to irritate your heart. I’m honestly so upset and depressed. I feel like I’m going to be worse off now that it wasn’t completely ablated AND that I went into afib. My svt was mild compared to some peoples and I’m so scared it will be worse. The reason I got the ablation was so I wouldn’t have to worry about episodes and now I’m more scared than ever.

Hi all- looking to see if anyone has a similar experience. I’ve been diagnosed with SVT but the episodes happen infrequently so I only take fleccanide when an episode happens (although that seems to have no effect- I also tried metoprolol with no effect). I’ve tried to figure out what my triggers are and I think lack of sleep might be my trigger. When episodes do occur, I usually take fleccanide plus drink water with LMNT which has potassium, magnesium, and sodium in it and that seems to be the only way to stop my episodes other than waiting it out. Has anyone else had similar experiences?

So basically im a teenager on the older side but 4 ish years ago I started having dizzy spells when standing and my heart would randomly start beating super fast no matter what I was doing. After 6 ish months it turned into random dizzy spells, heart palpitations, rapid heart rate when sittings, fainting (not often just sometimes), vision going dark when standing, shortness of breath, nausea, chest tightness/pain, and what feels like lung pain. The have all gotten worse overtime it’s been really hard. I have an SVT and WPW diagnosis but not much info on how to help it, I was told for two of those years it was just anxiety, I’ve worn 2 heart separate monitors. And my heart rate ranges from 40s - 180s every day I do take atenolol and it gets it down to 140s most the time but my meds don’t work like they used to so I am going back next week. I’ve heard stories of people only having episodes like once a day or week but mine are frequently to the point i cant even count them and last between 1-10 minutes each. ( I would like to note i love playing sports I used to play softball, basketball, and volleyball but now cant) i also know one trigger is heat it gets a lot worse in the heat. Any advice or anything helps!

So, I had an ablation that went great! It genuinely fixed the issue.
Today I had an episode, which I know is normal while the heart is healing, and I’ve been prescribed Deltiazem while it’s healing.
Anyone else taken this?
It helped get me back in normal rhythm and get my rate down. No side effects.

had an ablation today that was unsuccessful. the doctor said the way my heart is angled in my body created low visibility and was too close for comfort to the AV node. he told me he would not consider another ablation for many many many years. I’m 35. he said he ablated 7 spots around the origin and called it a partial ablation but was unable to ablate the origin. I’m seriously so depressed. SVT was ruining my life and I prayed this would be a cure. it effects what I eat/drink, my social life, and I feel like I am a shit mom with it bc I’m scared to go places with my kids. the doc said we will

have to wait and see if it helps at all but he was still able to induce svt with adrenaline after he ablated so to me that means it didn’t work

Hi sorry for the long post. I’ve been having heart problems for a while and was rushed to resus before Christmas with SVT (heart rate over 220 bpm). They terminated it with a vagal manoeuvre. Since then it’s continued intermittently; a 48‑hour ECG recorded 150+ episodes over two days, so I’m being referred for an ablation in June.

This Monday I was taken to A&E with SVT and very high blood pressure (about 180/120). I stayed around six hours and kept having very short episodes lasting seconds. I felt awful during and after. I’ve been prescribed beta blockers, but was told there’s nothing more they can do until the ablation. I will include a video of the heart monitor when I was having my episodes.

My employer has put me on sick leave as they don’t think it’s safe for me to be at work while this is happening. I’m struggling. it’s all happened so quickly and I haven’t had time to come to terms with it. I’m uncertain what I can and can’t safely do right now.

I’d appreciate any advice or support from people who’ve been through this,

Thanks in advance.

Anyone w svt what’s your resting hr is it lower or higher do you have other conditions

Is it common to have a higher hr?

Do you guys get this sudden dizziness like doom /death then heart rate skyrocket? I always get this dizziness like im a just fall over like my heart stops then bam shoots up

So I just met up with the doctor who’s gonna do the ablation. He warned me that there is a “low risk” that depending on where the problem is if it’s too close to the good parts there’s a small chance that when he zaps it it’ll zap them too. And as a result I’ll have to be put on a pacemaker. He said he’s very good, and in 20 some odd years he’s only ever had to put in two- BUT THATS A LOT MORE THAN ZERO.

So now that’s in my head. I’m wondering if this is a good idea at all now. Should I look for another doctor? Is this the risk worth it? *is 2 in 20 years a good record??*

Hello, sincerely want some help from those that have lived through it. I’ll be as short but through as I can

So, basically for the last maybe 12-16 years if I’m recalling correctly I’ve felt flutters it used to be for a couple of seconds etc being young I would just punch myself in the chest when it happened,didn’t think much of it. August of last year 2025 now at 32 I started getting this weird feeling in my chest like a pressure on my heart and palpitations was like that for a miserable 2 weeks or so. I drive a lot and at one point I had to call an ambulance and pull over they said It was just tachycardia went to MD after that they said acid reflux gave me omeprazole. My garmin gave me like 2 high heart rate notices I was like wtf but I didn’t feel the need to go to the ER December of 2025 just walking up stairs on the phone heart rate goes to like 140 per my watch rush to hospital thinking I’m having a heart attack I feel faint and light headed cold hands. They gave me I believe Diltiazem twice didn’t get me to normal until they gave me metoprolol. First they said it was afib but after discharge electro said it was SVT I was there overnight with an ecg monitor, had an echo they said everything was normal otherwise. Had a couple of palpitations since then here and there some scarier than others. Using a Kardia I’ve mostly caught a bunch of other stuff like supraventricular ectopy , premature ventricular contractions, wide QRS and only 1 reading of AFIB in hindsight those palpitations I felt 10-16 years ago feel more like the wide qrs readings I’ve had. I go weeks where I feel normal I can work out and feel awesome heart rate sits at 50-65 resting and weeks where my heart rate is higher resting Hr will be 75-85 and when doing basic things like walking gets me to 100-110 where as on my good weeks I would run 10 miles sometimes and my heart rate sits at 130-140. When I run on my bad weeks sometimes I hit 180s. Heart rate also goes up after meals some times. My concern is, could this be anxiety ( I don’t feel overly anxious except now with my health) some sort of hiatal hernia stimulating my vagus never. Or since I have been officially diagnosed with SVT should I just get the ablation i haven’t gone for a second opinion also. Just want to see if someone can relate. I have an appointment 6 months from now and I don’t know if I should just get this done.

Sorry for the hideous layout and punctuation. I’m on my cellphone. I appreciate your time if you’ve read this and hope you’re doing well.

***forgot to add have not been to the ER since and have had no other attacks since

I’ve been on the waitlist for my ablation since February of 2025, and I finally have a procedure date for June 5th! I’ve never had any type of surgery before; just wondering some tips for recovery! I’m 19 and I work an office job for the summer.:)

I take 75 mg but I feel like it doesn’t really lower my resting heart rate as much as it used to. I can’t take a lot of other beta blockers because they caused me to have asthma symptoms. Anyone with asthma have really good success with another beta blocker that isn’t the one that I’m currently taking. Please let me know because I’m probably gonna end up messaging my doctor to prescribe me it.

my resting heart rate isn’t necessarily dangerously high. It’s just much higher than it used to be, and I’m assuming my body built up like a tolerance.

I also feel like with the beta blocker. I have like high spikes of tachycardia still as well.

They also don’t want me to take Ivabrone with it and they said I can cause like a heart block. I’m also trying to think of other medications I could add with my beta blocker that will help lower my resting heart rate and make me feel more comfortable.

Just wanted to share my experience with Adenosine because I was scared shitless about getting it and just had it last night for the first time after trying to break it for 3 hours at ER while 31 weeks pregnant.

I am an anxious person and asked the doctor and nurses like 5000 questions and they were awesome at talking me through it leading up to it. I asked the one nurse who was working with me to use a more firm and calm tone. overly sappy “good job” scare me more.

They pushed it super quick, I didn’t feel anything for like 10-20 seconds and was like slay and then it was like a breath hiccup for a sec went to normal for a second and then I had about 2-5 seconds of more intense breathing trouble with chest tightness. The doctor verbally told me to breathe and someone blew air in my face and then I was able to breathe again. And I had instant relief and kind of a euphoria/adrenaline feeling. I had kicked my feet during the 2-5 seconds of the more intense chest tightness. It was so quick and the relief after was so worth it. I would totally choose that over waiting 3 hours in the future.

I just wanted to share because I came across so many scary stories of it. I wanted to present that sometimes it’s still uncomfy but 100% manageable.

Totally valid too if you’re reading this and did not have the same experience.

As the title suggests, i wonder what triggers your svt episodes. For me it is almost always explosive movements during sports, like a sudden sprint or jump. It has happened when i slipped once aswell.

Used my Kardia 6L and it caught this - is this SVT?
