The doctor may want your child to have some tests done before the electrophysiology study. These tests might include blood and urine tests, chest X-rays, electrocardiogram (EKG) and an echocardiogram. Often there is no required pre-procedural testing. If needed, the doctor will schedule these and tell you about them. These tests will help the doctor know more about your child before the study.
Sedation or anesthesia, medicines to help calm your child, may be used for the study. Do not allow your child to eat or drink anything from the time specified in your instructions until the electrophysiology study.
