Svt caused by air changes

I have had it where I get stressed out and drank too much caffeine or it can start for no reason. 

Hi Nichola. I don't think I've come across the air change SVT trigger before. I wonder if the trigger could actually be something else that's happening or being experienced at roughly the same time? e.g. the stress of flying...or you worrying that an air change will trigger SVT?

My common SVT triggers were caffeine (even decaff) until I realised, sudden bending movements, and mental or emotional stress (usually delayed). Most commonly though, especially as the years went by and I got good at avoiding the triggers, was no trigger at all I could identify e.g. just sitting relaxing.

As Linda mentioned, the ablation usually doesn't really care what your triggers or symptoms are. If successful, it corrects a tissue abnormality (we SVT folk are usually born with I think) that creates electrical confusion and causes the heart to go mad. 

I only wish I had had the ablation years earlier because being SVT-free has improved my quality of life immensely...

I hope you make the right decision for you and that it works out well. 

I was told by my cardiologist it is a misfiring of the electrical system in the heart. It doesn't mean you have a bad heart and it's not life threatening, it just makes you feel really bad.

He said its like when you go into a room and you turn on a light and it doesn't work. Hard to accept, but that's the way it is. Caffeine stimulates the heart and he also said stress may bring it on, but we all have stress, don't we? I have had it last anywhere from 15 minutes to 2 hours. It comes on suddenly and leaves just as suddenly. When I was in choir, I Kyle feel faint and heart racing- doctor thought maybe it was being under hot lights but still didn't call it SVT. Was at a restaurant, food had just came and suddenly my heart was racing and my abdomen became very distended. Went to ER. Doctors have been very perplexed with me. I thought it might be annirritated vagal nerve? Even though I'm a nurse, I still don't have all the answers. 

From what my doctors all told me, it's not really anything that can trigger your svt. It just happens. If we get them frequently (the attacks) and notice a pattern then of course we are going to try to avoid doing whatever we think causes it. But I would avoid certain movements thinking it would prevent an attack and I would still have an episode. It's all so confusing because it comes out of nowhere. I just recently had my abalation done on Tuesday and I already feel a huge difference with my heart beats. I used to get a lot of extra beats through out the day and now I don't. I did notice some last night but they were way milder than what they used to be. I hear it will all subside once the heart is fully healed. 

Mine is nearly always set off by bending down or stretching up, if an ectopic beat goes off as I do these movements it will start and SVT episode. Sometimes lying or sitting in a certain way will seem to cause me more ectopics and that might set of an SVT, and I did have one happen in my sleep that woke me up - that was the scariest one. I take Altenolol, have done for 10years, and I don't get attacks very often. If I do get one it is usually between 10 and 45 mins until it settles itself. Sometimes the vagus manouver of holding my nose and closing my mouth and bearing down will stop it, but not always.
