Part II. The technologist will then attach EKG electrodes to your chest in preparation for the Adenosine study. A cardiologist will inject a drug called Adenosine through your IV. This type of drug simulates the effects of exercise. The cardiologist will monitor your blood pressure and cardiogram. Another tracer will be injected into the IV.
Part III. There will be a 45 minutes wait before the last set of images.

The entire procedure will take three (3) hours.
What will happen after the exam?
After the exam, the technologist will process your images using a computer. A radiologist will compare the two sets of pictures within 24 hours and dictate a report. A report will be sent to your physician.
