When I was going through the grad school application process, I was also coordinating an international move. I became extremely stressed out, and manifested it through severe continuous chest pains. I ended up in the ER and had two separate EKG's done. It probably depends on how much lotion and how moist your skin is at the time, because I had a heck of a time getting those stickers OFF! They stuck a little too well. I think if you know well in advance that you're going to have an EKG, simply not moisturizing those areas should do the trick.
