Finally, an answer!!

Sorta. I kinda just self diagnosed myself (what else can you do when the doctors never seem to have an answer?).

Remember those chest pains I said I was having? How I was wearing the monitor but it never happened while I wore it (but it did pick up my unusually high heart rate)?

Check this out. This sounds EXACTLY like what's happening. Right down to the not being able to breath or move (which is really scary when it happens when I'm driving! Fortunately that's only happened once and I was at a stop light). It happened a couple times last week when we were on vacation, and I was worried about how often they were occuring (years ago when they started it was only a couple times a year, now it's around once a week or so on average). I'm glad to see that it's nothing to worry about, just a pain in the... well... chest!
