What Is an Electrophysiology Study?

An electrophysiology study tests the electrical activity of the heart to find where an arrhythmia abnormal heartbeat is coming from. The procedure is performed by having a small tube, or catheter, inserted into the patient’s artery or vein where it will be carefully guided to the heart. Small, electric impulses will be sent through the tubes to make the heart beat at different speeds. These signals from the heart will be recorded and this will allow the doctor to see where any arrhythmias are coming from. During the procedure, the patient is medicated in order to relax, however, they are usually conscious for the duration of it.
