Where I work our clinic pacemaker nurse interrogates devices. She sees alot of patients daily and ensures their device is working properly, and can change parameters to optimize therapy. She then relays pertinent information back to the electrophysiologist like when generators are needed to be changed, or if the device is not working correctly. She is an older nurse with alot of experience in cath lab, EP, and CVICU. She absolutly loves her job. She is the only one in the hospital that can do what she does. It seems to be demanding at times when she gets pages to go to the OR because surgeons need devices turned off or whatever. She really gets to know her patients, and she enjoys it. If your an adrenaline junkie then you should skip the clinic nurse and work in an EP lab or cath lab. I work in the EP lab and I get to see and do so much that not many others get to experience.
