I too am interested in the cath lab, I went one day to observe during school and I LOVED it so much I didn't want to leave
Ever since then I have had tunnel vision and I got a job on a tele stepdown unit ( I start in July after graduation in May) that gets post caths, rule out MI and EPS patients just to get the experience I need to go to the cath lab.... I can't wait to get there someday!! Good luck to you!!
