General instructions for Pacemaker or ICD implantation

Small device placed under the skin of the chest to regulate heartbeats.

  • Fasting: Strict fasting for 6 to 8 hours before the procedure is required. Small sips of water are allowed only for authorized medication.
  • Medication: If you take anticoagulants (such as acenocoumarol/sintrom, warfarin, rivaroxaban, apixaban, dabigatran, heparin, etc.) or antiplatelets (such as aspirin, clopidogrel, ticagrelor, prasugrel, etc.), they usually require suspension before the test (except for ASA 100 mg, which is usually maintained). However, it is ESSENTIAL that you follow the exact instructions given by your doctor. Review the consultation report in which the test was requested to confirm the specific guidelines for your case.
  • Clothing and Accessories: Wear loose clothes. Shirts that button in the front are recommended, as you should not raise the arm on the affected side afterward. Remove jewelry, watches, piercings, glasses, and any metal objects.
  • Specific Requirements: It is mandatory to be accompanied by a responsible adult. You will generally spend at least one night admitted, so prepare a bag with toiletries. You will likely be asked to wash with a special antiseptic soap.
  • Expected discomfort or pain from the test: After the implantation, it is normal to feel mild pain, swelling, or sensitivity in the incision area. It is well controlled with analgesics. You will feel the weight of the device under the skin, which you will soon get used to.

  • Mandatory requirement: If there is any possibility of being pregnant, it is strictly mandatory to report it before the test.*
