Intracardiac electrophysiology study (EPS) is a test to look at
how well the heart’s electrical signals are working. It is used
to check for abnormal heartbeats or heart rhythms.
Electrophysiology study - intracardiac; EPS - intracardiac How
the test is performed Wire electrodes are placed in the heart to
do this test. These electrodes measure electrical activity in
the heart. The procedure is done in a hospital laboratory. The
staff will include a cardiologist, technicians, and nurses. To
have this study: Your groin area will be cleaned and numbing
medicine (anesthetic) will be applied to the skin. The
cardiologist will then place several IVs (called sheaths) into
the groin or neck area. Once these IVs are in place, wires or
electrodes can be passed through the sheaths into your body. The
doctor uses moving x-ray images to guide the catheter into the
heart and place the electrodes in the right places. The
electrodes pick up the heart's electrical signals. Electrical
signals from the electrodes may be used to
