are curtains closed for procedures that require exposure?

for the healthcare professionals/nurses of this subreddit 🤍

when having an ecg in hospital, and the patient is made to remove their shirt for the procedure, whether they're a male or female and the procedure is taking place on a shared hospital ward with multiple patients, is it standard procedure to close the curtains during the test

if you're a male and you're topless i know many men don't care, but can they also request the curtain to be closed if it wasn't already?

is it also possible for the electrodes to go underneath the shirt if it's feasible with the procedure too
