Annie, I didn't read the whole article, yet. Waiting to refill my ink and print it out. TOO hard on my DV eyes right now to read the whole thing from the computer screen. I'll be sure and check out the anxiety part.
I seldom take offense with people who disagree with me. No diva personality here.

(Plus, I wouldn't last long at our family Christmas and Thanksgiving get-togethers -- LOL. They probably sound MUCH like your dad's debate team practice sessions did!!)
I wasn't actually LOOKING for answers to the heartbeat "question". I know of a young family whose father has been diagnosed with ALS after first being diagnosed with MG. I was just doing a search -- hoping BEYOND hope, ya know -- and ran across the tachycardia info during that search.
