Electrophysiology (EP) study is a detailed evaluation of the electrical activity in your heart, using cardiac catheters and computers to create electrocardiogram (EKG) tracings and electrical measurements from inside your heart. During this test, an electrophysiologist reproduces an abnormal heart rhythm and gives medications to determine which one best controls the rhythm.
You may need an EP study:
- To determine the cause of an abnormal heart rhythm.
- To locate the site of origin of an abnormal heart rhythm.
- To decide the best treatment for an abnormal heart rhythm.
Please consult your cardiologist for more information about an EP study.
