When I first started applying for EP jobs I had a nurse ask me if I even had an Anatomy or a Physiology, that was in 1990.
The staff's at hospitals really know very little of what classes we take to obtain a degree in EP.
If you interview at a hospital/ clinic educate them in what classes you took. Give then examples of your EP lab work and calculations and sell yourself as why you would be best an incredible asset to work in TMST or Cardiac rehab.
I was advised then as well, that the hospital was unable to bill for an EP because they were
"not licensed."
In order for me to get a job in treadmill testing and pay a mortgage, I had to become an registered nurse to get a job in TMST. We have nurses who had no training in exercise prescription running Cardiac Rehab. We need exercise physiologists, unfortunately the clinics I work at don't know it yet.
Sorry for rambling on and on
