Hi I have worked in a cardiology office for nearly 11 years now. When I first came there I was very unsure of my self. The other nurses were great teachers and were glad to have someone else there to help with the work load. All of the nurses were there to get out of the hospital as I was too so there was a quick bonding. The work in a office is diffrent than the hospital but can be just as challenging. As you learn what your physcian expects from you and you meet his expections he/she will trust you give you more autonmy to make decisions. That feels great. Learn your cardiac meds !!! I was very suprised at how many patients called with side effects. Study EKG's learn your abnormals. Consider taking ACLS because sometimes there are actually codes. If your practice is like ours you will be returnig patient calls adjusting meds, calling test and lab results and renewing prescriptions.You will also wonder how most of your patients ever did anything with their lives as most don't have a clue about their own health care. You will be fine, be confident, but not to cocky, show an eagerness to learn and don't be afraid to ask questions! Best of luck you will be great. Cardiac-Cath
