I'm glad you've had your heart checked out. It really does help me to take extra magnesium, when my heart seems to be extra sensitive.
Not to be gross.......but I've discovered that when I have stool in my transverse colon, it can give me ectopy! Maybe some of us just have thinner diaphragms, and our hearts get pushed on more easily by "stuff".
I've also been wondering.......I have a very high waist.......which means more stuff has to be fit into a smaller area. It makes me wonder if high waisted people tend to have this problem??
Even though I've had my heart checked out, ectopic beats are very disconcerting.
The one summer when I went to the ER for all the ectopics, and then had the stress echo, was when I was building a chicken run, and leaning over a whole lot.
I guess there's not much for us to do about it, except try not to lean over, especially when our stomachs are full! But like I said, I seem to get some relief from taking extra magnesium.
You're not alone with this curious problem!
P.S. Have you noticed that caffeine plays a part? I can have 1 glass of coke a day. But if I go to anything above that, my heart is alot more prone to ectopy. I've never figured out if its the caffeine, or the irritation to the esophogus.
