Electrophysiology (EP) Study

An Electrophysiologist is a trained cardiac specialist who would be performing an EP Study. This is a specialized procedure in which one or more thin, flexible wires, called catheters are inserted into a blood vessel (usually the groin) and guided into the heart. Each catheter has two or more electrodes to measure the heart's electrical signals as they travel from one chamber to another.

EP study or Electrophysiological study is mainly performed to diagnose cardiac rhythm abnormality, to help determine the best treatment, and to pinpoint the exact site where therapy may be useful.
