Q- How do I get ready for the insertion of the CRT device? 

You should discuss all the risks and benefits of the procedure with your doctor. He or she will probably tell you to not eat or drink anything after midnight before surgery. If you usually take medicines in the morning, ask your doctor if you can take them with a sip of water.

Your health care team may ask you to stop taking any medicines that thin your blood several days before the procedure. If you take medicines for diabetes, ask your doctor to help you adjust your dose around your surgery. Let your doctor know about:

  • Prescription medicines that you take
  • Over-the-counter medicines or supplements you take, especially aspirin
  • Allergies
  • Recent symptoms of colds or infections
  • History of problems with anesthesia
  • Inform your health care provider if you are pregnant.


Do not eat solid foods after midnight. If your procedure is scheduled for the afternoon, you may eat a light breakfast consistent with a clear liquid diet, including apple or white grape juice, clear broth, coffee or tea (Without milk or cream), and water.


Steps to follow before leaving home for your CRT procedure

  • Leave your valuables like jewelry at home.
  • Take a bath or shower before you come for the procedure. Do not apply lotions, perfumes, deodorants, or nail polish after the shower. 
  • Do not shave the surgical site yourself.
  • Bring a picture ID card. 
  • Bring someone to drive you back home as you might be under the effect of anesthesia and pain medicine. You may be required to stay overnight in the hospital after the procedure.
