What is Electrophysiology?

Electrophysiology refers to the electrical function of your heart. Electrical signals are generated by the heart to initiate the contractions of the heart muscle that pump the blood through the heart and out to the body.

An electrophysiology study, or EPS, is a diagnostic procedure that examines and assesses the electrical function of your heart. It is done in a cardiac cath lab to map the electrical signals created by your heart. EPS is a method of evaluating your heart rhythms as well as the disturbances of those rhythms. This study helps your heart specialist to determine the treatment option that is most appropriate for you.

Certain heart conditions can cause the electrical system to make the heart beat too slowly, too fast or in an otherwise irregular manner. These irregular patterns are called arrhythmias and they can happen in any of the heart’s four chambers. An electrophysiology study will help your physician determine the best treatment for you by showing where the arrhythmias are occurring.

What is an Electrophysiologist?

An electrophysiologist is a type of cardiology physician with specialized training that focuses on electrical heart function and rhythms. They perform the EPS diagnostic procedures and can diagnose and treat conditions and disorders that involve arrhythmias (irregular heart rhythm) and electrical function. Conditions like Atrial Fibrillation or another type of irregular heart rhythm as well as Tachycardia (fast Heart rate) and Bradycardia (slow heart rate). Electrophysiologists also perform the procedures such as pacemaker implants, cardiac defibrillators, and ablations that treat those conditions.
