Electrophysiology Study (EPS) - What it is

What is an electrophysiology study?

An electrophysiology study (EPS) is a minimally invasive procedure that tests the electrical activity and the conduction system of your heart. This test is used to find out the cause of any rhythm disturbance to the heart and determine the best treatment.

Examples of when an EPS is useful include:

  • Determining the cause of an abnormal heart rhythm
  • Locating the site of origin of an abnormal heart rhythm
  • Deciding the optimal treatment for an abnormal heart rhythm
  • Determining conduction system disease.

Once the electrical activity is recorded and the study is complete, your doctor may decide the optimal treatment for your rhythm disturbance is medication. If so, he will end the procedure and you will be taken back to the ward soon after. In other cases, he or she may decide that catheter ablation is best. If so, your doctor will most likely proceed directly to perform catheter ablation.

Note that you can have an electrophysiology study (EPS) without needing a catheter ablation, if your doctor determines that it is not needed.
