I had an experience different from Saber, but along the same lines.
I had a dizzy spell one night that my wife over-reacted to... so off to the ER I had to go. An EKG showed that I have Wolfe Parkinsons White (WPW), so immediately it was assumed that I had an episode of WPW and that's what I experienced. An episode of WPW is where the heart races so fast the person usually passes out. It happened to Meatloaf a few years ago while he was doing a concert.
So off to a heart hospital I'm sent, and they do surgery to try and ablate the WPW. Unfortunately I'm one of the 1% of people who have it where it exists so deep in a heart muscle that it cannot be ablated. So surgery failed to fix it, and I still have it. So now they want to treat it with meds. But they have to keep me in the hospital to monitor how I respond to the meds. Since I'm there for days on end with nothing to do, I begin to question if I even had an episode of WPW that night. The doc works with me on that line of thinking, and suggests we try a "tilt test". They have me lie on this board and strap me to it so they tilt me at a specific angle. Within minutes the exact same thing I experienced that night happened. My head starts swirling and a pass out. Doc said some people just do that when their bodies stay at that exact angle for an extended period of time. I now no longer watch TV tilted at that angle.
But here's where it gets sick. I now know what the problem was, and want to leave. But doc says, "oh no, no, no! You have WPW and it needs to be treated." Back then I was a lot more passive and respectful of doctors, so I said OK. Continue staying on the WPW meds in the hospital for days on end. Doc finally determines that the drug he tried on me wasn't producing the results he wanted to see, so he's moving me to a new drug. I say can I go on this new drug and go home. He says no.
At this point I say, given I've been bored out of my mind in here I've researched this WPW and I'm more likely to die in a car accident than I am from a WPW episode. and studies show that if someone has WPW but never had an episode of it, the older they get the less likely they will ever have one. He said all that is true, but the risk of WPW episodes is treatable, where as the risk of car accidents are not.
It was at that point I realized I was in that hospital room for weeks because I had something treatable and was covered by great insurance. And If I did not do something then, I would be in there for even more weeks, perhaps months. I said I'm done, and they discharged me. I've not taken a drug for WPW since, and that was over 8 years ago. Never had one WPW episode in my entire 44 years of living.
