So today I survived and they didn't cart me off on a gurney. The technicians and nurses won't (or can't) tell you what it looks like, so I have to wait for the doctor on Monday. Ahh... the virtue of patience for the patient.
With the use of a radioactive dye (that "lights up" the heart and other organs), they take a 3-D picture of the heart before the treadmill and another following. They used what they call a Gamma Camera.
Thanks again for those prayers and the notes and comments of encouragement!
I'll also weigh-in again on Monday!
