Electrophysiology is the study of the electrical activity of the body. An electrophysiology (EP) study is a test that records the electrical pathways and activity of your heart. These studies can help diagnose what is causing a person's abnormal heart rhythm (heart arrhythmia).

During an EP study, a specialized doctor, known as an electrophysiologist, inserts a thin tube called a catheter into a blood vessel that leads to your heart. The catheter sends electrical signals to the patient's heart and records its electrical activity. This process helps the electrophysiologist determine the cause of the arrhythmia to recommend appropriate treatment.

In addition to EP studies, the Sentara Heart and Vascular Center offers a variety of cardiac imaging and diagnostic tests.
