This advice sheet has been produced to give you information about your pacemaker generator box change procedure.  It is not meant to replace discussion between you and the healthcare team. If after reading it, you require further explanation please discuss this with a member of the healthcare team.

Wound Care

There may be some discomfort at first, near where the pacemaker box has been changed. You are advised to take pain relief medication such as paracetamol to ease the discomfort. Avoid pain relief medication that contain aspirin (although you should take prescribed aspirin in the normal way).

Keep the wound clean and dry and look for signs of swelling, redness or discharge.  If you notice any of these or have excessive pain at the wound site you should contact your doctor.  The wound is normally closed with dissolvable stitches or glue, which do not need to be removed. You will be informed by your nurse if there are any stitches to be removed.

If a dressing is applied this is usually kept on for 48 hours after the procedure unless the nurses tell you otherwise when you are discharged.  After this time, it may be removed and if the wound is clean and dry it may be left without a dressing.

If you have any concerns about the wound site you can either make an appointment to have it reviewed with the practice nurse at your doctor’s surgery or contact the ECG Department directly (01482 461537).

Once the dressing has been removed you may shower and bathe and female patients may wear a bra as usual. 

When to contact your doctor or seek medical advice 

If you experience any of the following, notify your doctor immediately.

  • Difficulty in breathing, dizziness of fainting
  • Prolonged weakness of fatigue
  • Swelling of the legs, ankles, arms or wrists
  • Chest pain or prolonged hiccupping

Identification card and follow-up

You will be given a new pacemaker identification card by the physiologist when your pacemaker is checked on the ward. It is important you carry this card at all times. In case of an accident, this card will inform those attending you that you have a pacemaker. This card supplies basic information about your pacemaker. 

General advice 

You should not drive for 7 days after the generator box change.

Avoid heavy lifting and physical activities for one week.

You may return to work when your doctor feels you are fit to do so, normally after 3 -7 days.

It is important you tell other doctors and your dentist that you have a pacemaker.

You do not need antibiotics for any dental or surgical procedure unless you have another problem with a heart valve. If in doubt ask your doctor.
