​​The purpose of an Electrophysiology Study ​is to review​ the electrical system of the heart so the physician will know best how to treat you.  The heart has an electrical system that controls how your heart beats.  When this electrical system is working properly, the heart usually beats between 60 and 100 times per minute.  The electrical impulse travels a pathway from the top of the heart to the bottom of the heart.  Sometimes, the electrical system is not following a normal pathway, and the heart may beat too rapidly or too slowly.  When this happens, the heart may not be able to pump adequate amounts of blood to your body.

Before The Test

  • You may be asked to stop taking any medicines that affect your heart 
  • Your heart will be monitored prior to the procedure. 
  • You will be asked to sign consent forms after your doctor has answered all of your questions.
  • Most patients are not allowed to eat or drink after midnight prior to the procedure.  Ask your nurse. 
  • You will be asked to empty your bladder prior to the procedure and to wear only a hospital gown. 
  • You may be given some medicine to help you relax before the procedure. 
  • You will be taken to the cardiac cath lab by wheelchair or stretcher. 

During The Test

  • You will be lying on a padded flat table.  Your heart will be monitored, and x-ray equipment will be around you.  The equipment is sensitive to heat so therefore, the room is kept cold. 
  • A numbing medicine (local anesthetic) will be injected into your groin area and a small catheter (tube) will be inserted into the vein in your groin. 
  • Small wires will be guided into your heart through the catheters in the groin.  X-ray equipment will be used to tell if the wires are in the correct position in your heart. 
  • The doctor will use the wires to attempt to determine what is wrong with the electrical system in your heart.
  • Inform your doctor how you are feeling during the procedure.​

Immediately After The Test

  • The catheter in your groin may be removed before you return to your room, or it may remain in place for a short time.  When this catheter is removed, a bandage will be applied and the site will be checked.  You will be ordered to stay on bed rest for several hours after the procedure. 
  • The doctor will talk to you about the results of the study and any necessary treatment plan.
