Electrophysiology Study (EPS)
Electrophysiology Study is a test to find out the cause of arrhythmia. EPS is an invasive procedure. Small wounds are made over the groin, under the clavicle or around the neck by doctors for access to arteries or veins. Catheters are advanced to the heart under X-ray guidance. Electric information was recorded at specific sites inside the heart. Tiny electric current is emitted to test for abnormality in the conduction system.
