I see this is an old post,...but,...I am an NP working in a Cardiology / Electrophysiology Practice. I see patients in the office M-F, I do rounds in the hospital two days a week, I am on call and do rounds every other weekend. My days in the office are spent seeing patients, interrogating devices, etc. I do not work in the cath lab. I'm usually out of the office by 5-5:30, my day starts at 0830. I am salaried, and though I make above the avg NP salary for my area, I would make much more as an hourly employee!! I absolutely love my job and wish I had made the change sooner!
