An Electrophysiology Study (EPS) is a special heart catheterization that studies the heart's electrical system. The test involves inserting long narrow tubes (catheters) into a blood vessel in your leg, and guiding them to your heart with the aid of a special X-ray machine. The catheters inserted can record the electrical activity within the heart and are used to help find the cause of a rhythm disturbance.
