Electrophysiology Study

Results

An electrophysiology study will show whether you have an abnormal heartbeat that needs treatment. (Sometimes the treatment is done during the test.)

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

  • Pregnancy.
  • Taking warfarin (such as Coumadin) and having problems keeping a safe level of the medicine in your blood.
  • Extreme anxiety that causes high blood pressure and irregular heartbeats.
  • Kidney or liver failure.
  • Not being able to follow directions during the procedure.
  • Not being able to lie flat.
  • Ongoing bleeding problems or infection.

What To Think About

An electrophysiology study can be scary. You may find it helpful to talk to your doctor ahead of time about your fears. If you are awake during the test, you can ask questions and let your doctor and others know how you're feeling.
