An abnormal rhythm may be stimulated on purpose by a doctor during the EP study so that the underlying problem can be identified. There are several ways EP studies may assist in diagnosing heart rhythm abnormalities, ( also called an arrhythmia). Learn more about what to expect at the Tidwell Procedure Center. Small, thin wires are inserted through the catheter to the heart. The catheter is guided up the vessel (artery or vein depending on the purpose of the procedure) towards the heart using our state-of-the-art 3D mapping system. Next, a thin, flexible tube (catheter) is inserted into a blood vessel, most often in the groin area (the crease of the leg where it bends when sitting).

Once in the cath lab, he or she will lie on a small table surrounded by heart monitors and other monitoring equipment, as well as a specially trained team of nurses, technicians and doctors who monitor the child and make sure he or she is comfortable during the procedure.Īn injection of local anesthetic is given under the skin where the catheter is going to be inserted. The child is also given a sedative before the procedure to help him or her relax and possibly even sleep during the procedure. This includes taking vital signs, having the child change into a hospital gown and starting any necessary IVs. Upon arriving at the procedure center, the child will be taken to a pre-op room where he or she is prepared for the procedure. The child's doctor will discuss the risks and benefits of the procedure with the child and family and require written permission (informed consent) from the child's legal guardians to do the procedure. Electrocardiograms test can tell doctors if the child has an arrhythmia or a variety of other heart conditions.Īt CHOC, we are able to provide a number of different types of electrocardiogram tests, including:Įlectrophysiological studies are performed in one of two state-of-the-art catheterization labs in the Tidwell Procedure Center at CHOC. These types of tests are done by placing electrodes at specific locations on the body and tracking the electrical activity in the heart. (These tests are also referred to as “ECG” or “EKG.”) An electrocardiogram measures the electrical activity of the heart and does not require our specialists to go inside the child’s body. The first type of electrophysiological tests is a noninvasive test called electrocardiogram. Our specialists work with each patient to determine the right type of tests needed. There are two main types of electrophysiological testing done at CHOC. Electrophysiological testing helps our pediatric cardiology specialists learn about the heart’s electrical system.
