SVT / adenosine. Questions!

[Fio1331]

I'm awaiting a hospital appointment to assess my episodes of SVT, which started recently and don't respond to the 'home remedies' so it's A&E and adenosine to reset me. Horrible and scary.

Meanwhile, I thought I'd run my questions past you forumites. I know you're not experts, but general thoughts or shared experiences would be welcome while I wait for cardio to see me ...

My episodes have gone on for approx 2-3 hours, by the time I've got to A&E, been assessed then been treated. How long might an episode continue if I didn’t/ couldn't get to a hospital? Do they 'burn out' eventually?

How damaging or dangerous are prolonged episodes?

Why do they use adenosine rather than a beta blocker (which I did have the first time as they thought initially I'd had a heart attack, before they discovered it was my electrics!). Adenosine is pretty drastic and I'm grateful it works, but it's no fun.

Grateful to hear any info that anyone might have (and all these questions are also on my list for my cardio appointment, whene'er that may be 😉).

hi , had adenosine 8 times in a 2-3 day stay at the hospital via emergency room.

Not nice at all !!! I think they use it as it works quite quickly.. next time please try lying on your back and putting your feet up against the wall .. give it a few minutes and your HR should drop back into sinus

Thanks for the reply. Unfortunately none of the lying, leg lifting, nose-holding, syringe-blowing etc etc work for me. Tried them all, as do the emergency doctors initially, before they resort to adenosine. Sigh. Still waiting for my appointment, and frustrated, although thankfully I haven't had another episode since I wrote this question.
