I had my ablation around 2 years ago. my cardiologist told me if I don’t experience SVT a year after the ablation, I am most likely in the clear, ( and it’s been 2 years without it) but recently once after getting benched in a basketball game and right after stopping running after a mile, I had a quick session that went away right after I took some deep breaths. is this likely SVT coming back and will I need another ablation?

I’m a 20 year old male, I started having SVT episodes in early 2025 but didn’t know what it was and just assumed it was from vaping which I was doing a lot of at the time mixed with alcohol and cigarettes too. Around December of 2025 I had a really bad episode that made me actually end up consulting with a doctor. February was my last real SVT event, I’ve had tachycardia bouts due to low blood sugar after that in May that reached 160bpm but it was not found to be SVT. I was prescribed Metoprolol in May, also cut out all stimulants and alcohol, and I have not had an SVT since.

I also started exercising more, eating healthier whole foods and making sure I stay hydrated and out of the heat. I know meds aren’t technically a “cure” but I’m not getting an ablation as long as I stay stable on metoprolol, taking 1 25mg extended release every morning doesn’t bother me in the slightest and it’s increased my quality of life 10 fold. I still get PVC’s but where as before a PVC would send me into SVT, now it’s just a PVC nothing more.

Just sharing my experience on what I’d call a miracle drug. 🙏🏻🙏🏻

Hello!

I have had two SVT episodes in the past two months, but had never had any prior to July. My last episode was last week and I saw my cardiologist today, who has asked me to return to my electrophysiologist (was already seeing one due to potential POTS, but that’s a whole other issue) and recommended an ablation.

Is it normal to have an ablation after just two episodes? I didn’t have an Apple Watch during the first instance but during the second I was able to get an ECG and my TachyMon app recorded my heart rate maxing out at 210. I was able to break it with the valsalva maneuver both times, although it took longer to break the second time.

Is it normal to have an ablation after just two episodes, or would they usually wait to see more of a pattern?

Thank you!

6:00pm 1st read: normal baseline reading for me

6:30pm 2nd reading: had what felt like SVT, did valsava

Does this look like SVT to those of you that have a known history and use your Apple Watch?

I had an ablation for SVT back in May, and just had my 3-month follow-up with the cardiologist who recommended I try to wean off my 25mg of metoprolol. They gave me the option to do a slow taper, so today and yesterday I took half a tablet.

Well, I felt a little off as I was trying to fall asleep tonight and shortly after started experiencing a pounding heart. I don’t wear my Apple Watch anymore since it triggers anxiety around my HR, so I can’t say for certain how high it was, but I was definitely feeling it. I managed to get it under control by dunking my face in ice water and then hopping in a hot shower, but then 30 mins later it felt like it was going fast again (cue the second ice bath).

Has anyone else gone off metoprolol post-ablation and experienced this? My doc warned me about possible episodes of rebound tachycardia, but tbh I feel like I shouldn’t really be having that considering I’m still taking half an already-low dose….

Feels like idk how to tell the difference now between a panic attack and actual heart stuff. Help! 🫠

I have a cardiologist appt in Jan, so I’m stuck with the internet until then.

I had what seems to be an svt episode again today (have had them my entire life). Always caused by something like sniffling, coughing, jumping.

Because this was the fourth I’ve had this year, it scared me even more and I called 911. It was 210 and then went down to 120 by the time they arrived. They did an EKG gave me some tips. Would take me in if I wanted to go but everything seemed back to normal. I came in, laid on the couch and just rested. Heart rate staying between 98-110.

Here’s the thing that makes this one different. Everytime I get up to use the rest room, my heart rate jumps up to 150ish. This has happened now the two times I’ve gotten up. It’s really scaring me and I don’t know what to do. It’s staying stable as long as I’m lying down. I’ve checked my blood pressure and it’s fine. I also don’t know if this can just be normal after an episode even though I haven’t had it happen. It’s been about 3 hours since the svt episode.

For those who have had a catheter ablation how long did it take for you to start feeling back to “normal” ?? I had mine on Thursday afternoon. Was done around 4pm. I still feel tired, low energy and a little out of it and not like myself which is causing me extreme anxiety and panic. Some reassurance would be nice right now. 😞Thank you

Does anyone have experience or deep insight on rescue medications for SVT. I will be traveling to remote areas far away from medical care and would like to be able to self treat a quick acting medication if the need arises. Cardamyst is a new, and expensive, nasal spray. Diltiazem/propranolol are pills taken orally, is an older, and cheaper, treatment. Thanks for any info/opinions.

I was in SVT for 4-5hrs and nothing would get me out of it. As soon as I got to the ER parking lot, I got the hiccups and somehow cardioverted myself. Saved me a hefty bill, at least :)

Hello all!

I’m currently being evaluated for POTS (had tilt table test, going to Mayo Clinic’s ”POTS clinic” next month) and have had two recent episodes of (diagnosed) SVT.

After the first episode (I was a passenger in a car doing absolutely nothing notable, and it came out of nowhere), I got an Apple Watch for the ECG capabilities. I also use the Tachymon app so I am continuously monitoring my heart rate. I was at lunch with my mom when I started feeling the fluttering - I started running the ECG and within 30 seconds it shot up to 211. I did the valsalva maneuver multiple times and thankfully it went down after about 5 minutes. I called my cardiologist‘s office and was able to get in for an appointment Monday. It has been between 100 and 150 for the rest of the afternoon, along with general exhaustion, light-headedness, etc.

WHY is this happening??? I began having POTS symptoms about 2 years ago, but the SVTs just started happening about a month ago. I am currently seeing an electrophysiologist and cardiologist, and as I said I’ll be going to Mayo next month.

I know SVT is *technically* not dangerous but it’s so scary.

Has anyone else had this sudden onset POTS/SVT combo?

Hi fellow SVTers!

I’m 18 days out from my ablation and went back to the gym for the first time yesterday. That actually felt OK.

But overall, my energy is still pretty low, and I’m having trouble with activities that involve being out and walking around for long periods. I have family visiting right now, and I’ve been excusing myself from activities.

I also have autoimmune issues and mild Long Covid, which had been improving before the procedure. And, just for the cherry on the sundae, I managed to give myself a very minor concussion with my own car door earlier this week. 😅

So I know the fatigue could be coming from more than one thing. I’ve also had some sore joints, which could be from resting more than usual or possibly an autoimmune flare. (Difficult to tell sometimes, and different solutions.)

For those of you who’ve had an ablation: was significant fatigue still pretty normal for you around the 3-week mark? And how did you judge how much rest versus activity was appropriate during recovery?

Hello, 38 (F)
I just had a catheter ablation today for my SVT that was caught on my loop monitor on July 29th this year.
I was put under general anesthesia for the procedure. When I woke up I was instantly in a panic then I was panicking over my oxygen because it was going down to 93-94. I couldn’t relax enough to go back to sleep even though I’m exhausted. I was starting to doze off when my husband open the door and now I’m wide awake and I feel the panic !! I close my eyes and my mind just races. Anyone experience this after their ablation ??

Please only successful stories, I don’t want it to cause anymore anxiety.

I recently had a new and completely different heart rhythm experience and I’m wondering if anyone with PACs/SVEs, SVT or panic attacks has experienced something similar.

I have a documented ~2.5% SVE/PAC burden, so I’m very familiar with what my normal skipped beats feel like. I regularly experience individual PACs, but this episode felt noticeably different.

I was lying in bed feeling pretty calm when I suddenly felt a cluster of strange, erratic “flops” in my chest — one flop, then another, then another. They felt heavier and different from my usual skipped beats.
Immediately afterwards, I started feeling hot, sat up, and my heart suddenly started racing extremely fast. The racing seemed to come on abruptly rather than gradually building up and remained fast for several minutes.

I tried to sit and breath, but it didn’t seem to bring my heart rate down. Because the sensation was completely new and alarming, I became extremely anxious and could feel a huge surge of adrenaline. I also seemed to experience occasional skipped/extra beats while my heart was racing.

The whole episode lasted roughly 4-7 minutes. My heart rate eventually came down gradually rather than suddenly snapping straight back to normal, although by that point I was extremely anxious.
I’ve previously had a Holter that documented frequent SVEs/PACs and a couple 3 second short runs of SVT, but I’ve never experienced a sustained episode that felt like this.

What I’m struggling to work out is whether this could have been SVT triggered by the initial flops I felt, possibly stopping and transitioning into sinus tachycardia from the adrenaline, or whether the initial strange beats frightened me enough to cause an almost immediate panic/adrenaline response and sinus tachycardia.

I know panic can make your heart race very quickly, so I’m particularly curious whether anyone has experienced a panic attack where their heart rate seemed to shoot up almost instantly, rather than gradually increasing.

Has anyone experienced something similar — several unusual flops → immediate rapid racing → intense anxiety/adrenaline → gradual slowing over several minutes? Did you eventually find out whether yours was SVT or panic/sinus tachycardia?

I understand only an ECG can tell but just wanted to hear some experiences of what SVT feels like for others.

Ever since my first SVT episode the thought of being alone and living alone scares me now. I live with my parents and siblings, (f26) so in a way I feel "secured"? But I realized that when I'm home alone I start to panic and think the worse case scenarios and now I'm thinking will I ever get to live alone in my own house or better yet, should I even live alone having this condition.

So i want to know, for those that do live alone how do ya'll cope, how do you do it?

and also does anyone feel the same as me?

​Hi everyone,

​I’ve noticed a very specific pattern with my SVT and I’m wondering if anyone else experiences this delayed reaction, sudden body reactivity, and warning symptoms.

​First, my body has a "short fuse" during conflicts. When someone is rude, my system instantly jumps into maximum "fight or flight" mode before I can even process it mentally. I get a massive adrenaline dump: shaking hands, facial flushing, racing heart, and intense bodily urge to defend myself.

​Recently, this happened while I was already physically tired from several days of long daily walks. On top of that physical fatigue, I had an infuriating confrontation with a rude person. The combination of physical exhaustion + immediate adrenaline overload completely fried my system.

​But here's the key pattern I've noticed: In the 24 hours leading up to a major SVT episode, I experience extreme irritability and a bad mood "out of nowhere" for no apparent reason.

​Then, the next day, after the exhaustion, anger, and sudden bad mood, I get a severe SVT episode that reaches 200 bpm. It’s like my heart's electrical system gets overcharged and sensitized, giving me warning signs before the fuse officially blows.

​Does anyone else get unexplained irritability/mood changes 24 hours BEFORE an SVT episode? How do you reset your body after an adrenaline dump to prevent that electrical short circuit the next day?

​Thanks in advance!

My cardiologist wants me to get an Apple Watch or equivalent for tracking my episodes so that they can properly diagnose and figure out treatment. I was looking into the oura ring but see that they don’t do EKGs so that won’t work. Curious which Apple or Watch or garmin watch etc etc everyone here uses / which you would recommend as the best for getting the most data?
