Or you can trim it before hand and they shouldn't have to shave it. My nurse didn't have any issues getting a signal and it didn't hurt removing the stickers.Fair warning to anyone that hasn't done their doctor's appointment yet. When it gets to the point where they do the EKG and the nurse goes "Well, we'll see if we can get a signal first before shaving your chest" just tell them to shave it. You do not want to pull those stickers off and then just end up having to get the razor anyway.
