Actually, since it's only going to be 24 hours I'm not sure if I'll be getting a holter or event monitor. I've had holters on me 3 or 4 times now (and as many EKGs too), I had the electrode pads residue to deal with. Unfortunately, acetone is what they use in nail polish remover, so I already know I can't use that on my skin.
So fair, a couple of showers and a lot of scrubbing has removed the residue before. No problems with dresses here, I can't wear them unless I want to sew/alter one to fit me. I suffer from too much on top and no butt problems - so dresses hang like sacks.
If it is a holter, and the same model I've had so far, they're fairly large... and the stupid electrode leads never stay clipped! Hopefully though I'll find out what else is going on besides tach, I suspect PVCs (most people have them), who knows what else they'll find.
Hopefully, if your heart is doing funny things, all those weird yoga positions will set it off and your event monitor will catch it. When I bend/lean over, or try to support to much weight (lifting anything) it sets off my ANS - my heart rate either goes up or down and my blood pressure drops.
And I do have some hypermobility, while strengthening my joints probably would help a lot, if I move the wrong way I can actually partially dislocate a few of my joints. Hips and shoulders are the most noticeable for me. I'd probably have to try yoga aimed about people in their 50s.
Did you ever mention the possibility of dysautonomia or partial dysautonomia (POTS, NCS, PAF, gastro motility issues) to your doctor? Were you taken seriously?
