What is the longest SVT episode you’ve ever had and how fast was your heart rate.

Hey, I'm around your age, I'm 22. Have had SVT since I was 10. Happened like clockwork throughout my childhood and teen years, very severe. The year I was 17, after being put on Atenolol, I didn't have any SVT at all. Then just some tiny episodes when I was 18-19, and I thought it was mostly gone for good. I was pretty happy about that. Then, bam... just after my 20th birthday, I had the worst SVT I'd ever had. Up until that point, even though it was bad, my heart had always reverted on its own. But that day, it just didn't stop.

I was in a restaurant when it happened, went to the bathroom, laid on the floor (ew), hoping it would stop. I tried loads of techniques and it didn't stop. Went home and popped a few Atenolols, still didn't stop. Took loads of Magnesium, that didn't stop it either. The beta blocker and Magnesium definitely lowered my pulse, but I was still in SVT, which was a strange feeling. It just didn't want to stop. Then went to hospital and had the Adenosine. Very strange feeling. Stayed overnight and was officially diagnosed the next morning... and was given Verapamil, which I still take. All in all that episode probably lasted 3 and a 1/2 hours from when I got it in the restaurant till they injected me in the hospital.

A few months after that hospitalistion, whilst on Verapamil, I had one breakthrough episode. I was two minutes away from the hospital, so I went right in. I got into the hospital bed, and some nurses started examining me, setting up an IV. Then a cardiologist came in and massaged my neck artery whilst he was examined me. That was enough to revert it! So it lasted probably only 30 minutes. Maybe he was a super talented doctor, but I'm inclinced to think it was the Verapamil that made it so much easier to revert to sinus rhythm. At first I was bummed that I had a breakthrough episode even when taking Verapamil, so my dose was increased. I now take a pretty high albeit safe dose. And it works! That episode was almost two years ago now! So I haven't had an SVT in two years. 😃 And that's wonderful to me. Even though I have to take medicine, I feel like I have my life back. I still feel fear in certain situations that used to induce the SVT, but I remind myself that, thanks to Verapamil, there's only really a 0.000001 chance that I'll ever get it again. And if it were to happen, it would revert quickly.

I know a lot of people are against taking drugs, but for me, there wasn't really any other choice. Ablation isn't really an option for me for other reasons, so I'm honestly just so happy that the meds work. In my case, the advantages hugely outweigh the disadvantages. I've had pretty uncomfortable ectopics recently, but it's a much better alternative than SVT. My SVT was so persistent and scary that anything to keep it at bay now is a good thing. I'm particularly passionate about keeping it at bay because I started having it when I was so young and so scared of it, and it really affected my quality of life, especially because my parents never took me to the doctor to try and diagnose it, so I was just left on my own to deal with it. I really won't allow it to interfere with my life again. Things are good! Thankfully we have medication that can help SVT, and, in my case, completely eradicate it. And for many people, ablation works well. Hope things get better for you, if you ever want to chat about being young and having SVT, just message me.

Mine are always over 200 beats and they can last up to 1+ hours. However my cardiologist tells me to go to the ER if it doesn't stop in 10 minutes! I used to follow her advice, but now I wait and keep trying to break it ....so I can avoid the wait time and adenosine in the ER.

248 bpm and it lasted over 90 minutes until they converted it at the ER with Adenosine. All other SVT attacks were 30 minutes or less so I never even had a chance to go to the ER.
