In this article. An electrophysiology (EP) study is a test that records the electrical activity and the electrical pathways of your heart. This test is used to help determine the cause of your heart rhythm disturbance and the best treatment for you.
Electrocardiogram â Tracing of the electrical activity of the heart. Electrode â Medium for conducting an electrical current-in this case, platinum wires. Electrophysiology â Study of how electrical signals in the body relate to physiologic function. Event recorder â A small machine, worn by a patient usually for several days or weeks, that is activated by the patient to record his or her EKG when a symptom is detected.
