What is an electrophysiology (EP) study?

ANSWER

This test records your heart’s electrical activity and its electrical pathways. The results help pinpoint the reasons for your heart rhythm disturbance, and how best to treat it. During the EP study, your doctor reproduces your abnormal heart rhythm. They may give you different medications to see which one controls it best, or to decide on the best procedure or device to treat the condition.
