You will lie on a bed, and the nurse will start an intravenous line (IV) in your arm. The IV is used to deliver medications and fluids during the procedure.
A medication will be given through your IV to make you feel drowsy, and you may fall asleep.
Your neck, upper chest, arm and groin will be cleansed with an antiseptic solution, and the catheter insertion site(s) will be shaved. Sterile drapes will be placed to cover you from your neck to your feet.

The doctor will insert several catheters through a small incision into a large blood vessel, and It may be necessary to use both an artery and a vein. A transducer is inserted through one of the catheters so an intracardiac (inside your heart) ultrasound can be performed during the procedure. The ultrasound allows the doctor to view the structures of the heart.
You will feel a burning sensation when the doctor injects medication in the catheter insertion site.
You may feel your heart beating faster or stronger when the doctor uses the pacemaker device to increase your heart rate, and you may feel some discomfort or a burning sensation when the energy is applied.
