Why might I need an electrophysiology study?

An electrophysiological (EP) study, an invasive procedure that tests the heart's electrical system, may be performed for the following reasons:
  • To evaluate a symptomatic patient (a patient having dizziness, fainting, weakness, palpitation, or other symptoms) for a rhythm problem when other noninvasive tests have been inconclusive
  • To locate the source of a rhythm problem
  • To assess the effectiveness of medication(s) given to treat a rhythm problem
  • To evaluate the effectiveness of a pacemaker
  • There may be other reasons for your physician to recommend an electrophysiological study.
