title: Electrophysiologic testing.
abstract: The purpose of this article is to provide an introduction to electrophysiology (EP) testing. The history and evolution of EP testing will be reviewed briefly. The indications for electrophysiology studies (EPS) testing, EP definitions and terminology, components of a basic EP procedure, and potential complications will also be presented. To understand the principles of EPS, comprehension of the heart's electrical properties is imperative.
