An electrophysiology (EP) study is a test performed to assess your heart’s electrical system or activity and is used to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and then wire electrodes, which measure electrical activity, through blood vessels that enter the heart.
How do I prepare for the test?
Don’t eat or drink anything for 6 to 8 hours before the test.
Tell your doctor about any medicines you take, including over-the-counter medicines, herbs and vitamins. He or she may ask you not to take them before the test. Don’t stop taking your medicine until your doctor tells you to.
Have someone drive you to your appointment and take you home.
If you usually wear a hearing aid, wear it during your procedure. If you wear glasses, bring them to your appointment.
What happens after the test?
- You’ll be moved to a recovery room for 1 to 3 hours. During this time:
- Stay still as long as your nurse tells you to. Be sure to keep the arm or leg used for the test straight.
- Your nurse will check for bleeding or swelling at the puncture site.
Before you leave, you’ll be told what to do at home.
