Electrophysiology Study Home Care

(757) 668-7000

An electrophysiology (EP) study is a test that helps the doctor know how your child’s heart beats. An EP study is done by putting small tubes (catheters) into the heart through a large blood vessel in the leg. The test shows where the extra heartbeats come from in the heart, and if they are dangerous. The test also shows what types of medicine will best help your child’s heart.


  • The doctor will decide after the test if your child can go home the same day or the next morning.
  • Two adults may come into the Post Anesthesia Care Unit (PACU) after your child returns. The nurse will be checking the dressing and the pulses in your child’s foot every 15 minutes for the first hours.
  • There will be a Band-Aid® or small dressing over the site. This is usually at the top of one or both legs in the groin area. The doctor will tell you when the dressing can be removed, usually 6-8 hours after the test.
  • The site may have some bruising and may be sore for a few days.


  • Your child needs to lie down quietly as much as possible and not move or bend his/her leg or arm for about six (6) hours after the test.
  • A quick shower or bath is okay but the insertion site should not be put under water for 2 days.  Avoid swimming until scab forms.
  • Start giving your child his/her normal medicines as discussed with your child’s doctor.


  • There is steady bleeding or a growing lump at the insertion site, press on the site firmly with a clean cloth for 5-10 minutes. If this does not stop the bleeding, call your child’s doctor.
  • Your child’s leg or arm changes colors. For example, if it becomes blue or dusky when compared to the other leg or arm.
  • Your child’s temperature becomes greater than 101.5 rectally or by mouth.
  • The insertion site becomes red, warm or has yellow or green drainage.
