Cardiac Electrophysiology and EPS

Cardiac electrophysiology studies (EPS) are tests that allow your cardiologist to identify the nature and causes of an arrhythmia. Electrophysiology studies, conducted in an EP lab or catheterization lab, test the electrical activity of your heart to determine where your abnormal heartbeat is coming from. By identifying the source of the arrhythmia, your doctor will be able to decide the best course of treatment, which may include medication, a pacemaker or implantable cardioverter defibrillator (ICD), cardiac ablation or other surgical options.

To perform cardiac electrophysiology studies, your doctor will insert a catheter into one of the blood vessels leading to your heart. This catheter sends electrical signals to your heart and records its activity. The results of EPS testing can tell your doctor why your heart isn't beating normally, where the arrhythmia is located and how well your medications are working to treat your arrhythmia, as well as measuring your risk for sudden cardiac arrest and other complications. These results also guide decisions on next steps for treatment.
