Electrophysiology Procedures (EP)

An EP (electrophysiology) study is an invasive procedure often done on an out-patient basis. It focuses on diagnosing the source of the patient’s symptoms and localizing the problem to a particular part of the heart. The results of the EP study determine the next step (ablation, pacemaker, defibrillator or medical therapy) which may or may not be done at the same time.
