Electrophysiology

Also known as: cardiac electrophysiology, intracardiac electrophysiology.

What is electrophysiology?

An electrophysiology study is a medical test that examines the heartbeat and the heart rhythm. The purpose is to identify and determine the possible type of abnormal heart rhythm (arrhythmia) present.

What happens during the test?

During the test, electrodes that measure the heart rhythm are placed inside the heart. In order to do this, sheaths are inserted into the body at the groin or neck. Specialized catheters with electrode wires inside are inserted through the sheaths and guided to the heart with X-ray technology.

Is any special preparation needed?

You may need to stop taking certain medications before the test. You will also likely need to not eat or drink anything for 6 to 8 hours beforehand.

What are the risk factors?

Bleeding, infection, clots, vein injuries, heart attack, or stroke are potential risks of this test.
