Last year, I had a Nuclear Stress Test & passed it okay, but by the time it was over, they had to put a chair on the treadmill for me to sit in, cuz I was about to pass out completely.
But, as I recall, I didn't have any AF after that test, but did have a couple episodes of it the following week. 1 lasted about 1 hour & the other about 2 hrs.
I hate living w/AF.
But I am so very afraid of dying young too. I'm 59.
I've dealt w/AF since 2004, & the goofiest thing I've ever heard about AF is the fact that it duzn't damage the heart, or so that's what my cardiologist said. Weird.

It sounds like you have paroxysmal A fib, which is different than mine. Mine has been continuous since I was diagnosed on March 11. It's hard to imagine it doesn't damage the heart, since I seem to be hearing eventually it causes heart failure. But then I hear so many things and my doctors don't want to spend any time explaining anything.

Yeah, I don't understand doctors period. They remind me of lawyers, in that none of them can ever completely agree on any diagnosis, much less treatments. No wunder they're constantly in court w/each other.
Like lotsa people, when the AF first happened, I thought about what would happen to me if I couldn't work any longer & how would I be able to support myself. I still think about that. But, since last May, I have a less stressful job, & grrreat medical benefits, so that's less on my mind each day.
I wish I could retire, but a lot of companies, my employer doesn't have medical benes for retirees.
Bummer.
Plus, since I've had breast cancer & chemo & radiation in 2005 for 4 straight months, my oncologist told me that chemo will damage the heart (not could damage it). So, needless to say, that rotten episode has racheted up the AF episodes I have experienced.
I hate taking so many pills daily. No one knows what any medication duz to the heart itself, especially after taking it for a few yrs. It's the long terms effects that lotsa doctors refuse to talk about sometimes. I'm sure for professional reasons, they're careful to limit 'speculations' to their patients.
Having to live w/the after effects of cancer, TIRED every single day & AF dogging me, my friends have stopped asking me to travel w/them. They never say anything about why, but I know they wouldn't want to be around someone who has to stop & sit a lot.
Sometimes, I think that just maybe, if I have an AF surgical procedure, that maybe I'd feel good enuff to travel again. . .
I dunno.
I hope you have the BEST RESULTS of whatever test or procedure you choose to have done.
Oh, & yes, prayer duz work.
