rpm, I have had 2 of the 'big ones'.
Had to put the paddles to me. Just like going to sleep > no out of body experience or any Perley Gate images or angels holding my hand. The worst part of the whole deal was sandbag and not being able to move after the operation.
The big mistake people think is that there is always chest pain (that is only in the movies). Not all the time, for with each of mine there was none at all. Only thing that saved me for the 2cd one, 3 years later, was I knew what other symptoms to look for.
The doc was quite surprised when I gave him a running commentary on where the end of the stent probe was as it went through the body.
Quiting smoking was no big deal as the hospital stay was 10 days. Several days in ICU and then a wait for a transfer to the Heart Institute across town. After getting out, the smell of cigarette smoke made me want to puke.
I would be in the poor house if it was not for Medicare.
