Electrophysiology Study (EPS)

An electrophysiology Study (EPS) is a look at how well the heart's electrical signals are working. It is used to check for abnormal heartbeats or rhythms. Sedation is provided during the procedure. This specially-trained Electrophysiology Cardiologist will give localized medication before placing an IV into the groin area and then special wires are placed in the atrium and/or ventricle along the conduction areas of the heart. These special wires record electrical signals and the spread of the electrical impulses during each heartbeat. The electrodes can also give electrical signals that may make the heart skip beats or produce an abnormal heart rhythm. This can help the doctor understand what is causing the abnormal heart rhythm. Your doctor may also give medicines to help the abnormal heart rate to occur. The special wires can help to identify the areas of the heart that are causing the problems and help the doctor determine how to treat the patient.
