Fred,
That is great news and I know that you are relieved. Hope that it never happens again.
Kristen,
I have a similar but less serious problem with my heart and have had it all my life. At time I will get a pain that is so bad I can hardly breathe. It may last a few seconds or a minute and then just quit. Had every test they know of and they really can't find anything but a minor heart murmur. And one other possible thing that I don't know what means. After numerous tests they concluded that my nerves actually cause the muscles around the heart to press against and I should immediately take several nerve pills and lay down for a few minutes. That works and it seems to be getting longer between those spells, but I am also taking more medication than I did before. Oh the fun of finally starting to get old. 10,000 years ago I would have passed it off as bad meat.
