Cardiac Stress lab Nurses

Hello Nurses,

I'm a new RN grad with a possibility of a job in the Stress lab. I have look up information on the job description. If there's anyone who actually works in a cardiac stress lab, can you tell me exactly what you do? What information/ books will help me with increasing more knowledge. I was a LPN for three years with a cardiac background. What meds do I need to know, and more importantly what do I need to do for my patients.

Thank you all,
