Electrophysiology
An EP Study is a specialized procedure conducted by a trained cardiac specialist, the Electrophysiologist. In this procedure, 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 studies are done to diagnose your cardiac rhythm abnormality, to help determine the best treatment, and to pinpoint the site where therapy may be useful.
