Now, let's discuss what will happen on the day of your procedure.

At your scheduled time, you will be taken to a procedure room. To prepare you, your healthcare professional will first make sure that you have an intravenous or IV. You will receive fluids and drugs to help you relax during the procedure.

Patches also need to be applied to the skin of your chest, arms, and legs for electrocardiogram, or EKG. An EKG records the electrical activity of your heart.

An automatic blood pressure cuff will be placed on your arm and to check oxygen levels in your blood, a pulse oximeter, which is a measuring device, will be taped to your finger.

Your doctor may be available to answer any last minute questions that you may have.
