An electrophysiology study (EPS) closely monitors your heart rhythm. EPS can help determine exactly what your rhythm problem is and what can be done to control it.
Dignity Health Heart and Vascular Institute of Greater Sacramento provides exceptional diagnostics for our heart and vascular patients. Our physicians use the latest technology to ensure an accurate diagnosis so we can provide you with the best course of treatment available.

Other procedures that may be done during the study include defibrillation (electric shock to the heart to help adjust the heart rhythm) and catheter ablation, a procedure that destroys an abnormal electrical pathway or cells in the heart. After the electrophysiology study, you usually remain in the hospital for several hours or overnight. During that time:
