I had to wear one too (periods of chest pain).
My biggest suggestion is that if you get the chance to get copies of your strips and 12-leads don't! You'll over analyze things to the point of obsession. Things you'd brush off as nothing for one of your patients will seem like the end of the world on yours. At least that was my experience
But at the same time, do get copies.... you want them for your own records. It is always good to have an old ECG to compare to just in case.
So I guess what I'm saying is DO get copies and DON'T look at them
