Electrophysiology Studies


This is a test to look at how well the heart’s electrical signals are working. It is used to check for abnormal heartbeats or heart rhythms called arrhythmias. These tests can also help determine how well your medications are working or if you might benefit from a pacemaker or implantable cardioverter defibrillator.

In this test, you will be given an IV in your arm to help you relax. A local anesthetic will also be used to numb the area where the doctor will be working. The doctor will then insert a sheath into your artery or vein. The doctor uses the sheath to insert several long, flexible tubes called catheters into the blood vessel and move them to your heart. The doctor then sends small electrical pulses through the catheter to make your heart beat at different speeds, which can help locate where an arrhythmia is starting.
