I work in a cardiology office with 6 MD's. We do up to 8 nuclear stress tests each day. One of the RN's monitors the stress test. A doctor is required to be in the office before we start. All of our nurses, MD's and nuclear tech's are ACLS certified. My father-in-law had one done in my office in November 2001, and infarcted during the test. I was pleased at how quickly I was pushed aside as my co-workers responded to the situation.
