Can too much pressure on the chest make one's heart stop?
How I was sitting for almost an hour last night put enough pressure on my chest to where I couldn't take a full breath. (I wanted to see if I'd be able to handle a corset. Guess not.) After a while, I suddenly got dizzy and it felt like my heart stopped for several seconds, and that's when I stopped. But I've been worried about that ever since.
I should clarify that this was last night, almost 12 hours ago, and I'm mostly worried about whether or not there's still any danger now of anything happening as a result of last night.
