Test Overview
An electrophysiology
study, or EP study, is a test to see if there is a problem with your heartbeat (heart rhythm)
and to find out how to fix it.
In this test, the doctor inserts
one or more flexible tubes, called catheters, into veins in your groin, arm, or
neck. Then he or she threads these catheters into the heart. At the tip of
these catheters are electrodes, which are small pieces of metal that conduct
electricity. The electrodes collect information about your heart's electrical
activity. Your doctor can tell what kind of heart rhythm problems you have and
where those problems are.
Sometimes the problem can be fixed at the same time. A procedure called
uses the catheters to destroy
(ablate) small areas of your heart that are causing the problem.
