Sounds like the full workup. I did the same stuff, all mostly harmless. The heart monitor sucks. Try to shave your chest (might take a while for a hairy chewbacca) above your heart before you go into that, otherwise they will "dry shave" it for you and it gets itchy quick and you cant scratch it under the monitor. They made me bleed with the dry shave and it bled under the heart monitor sticker so I had an itchy blood bubble for 2 weeks. Took me 4 months to get into a cardiologist ... small town problems.
Did the EKG show any palpitations?
