Pacemaker Implantation

What is a Pacemaker Procedure?

A pacemaker implantation is a specialised procedure used to treat certain heart rhythm disorders by implanting a small device called a pacemaker. A pacemaker helps regulate your heartbeat if it is too slow or pauses inappropriately. The pacemaker sends small electrical impulses to your heart, ensuring it beats at a steady rate.

Before a pacemaker procedure, your Specialist will provide detailed instructions on how to prepare. This may involve fasting and adjusting medications such as withholding blood thinners. The procedure is typically performed in a cardiac catheterization laboratory (Cath lab).


During the procedure, you will be given sedation to help you relax, and the insertion site will be numbed with a local anaesthetic to minimise discomfort. Your heart rate and rhythm will be continuously monitored throughout the procedure.


The pacemaker leads (thin wires) will be inserted into a vein near your collarbone and guided to your heart. Once in place, the leads will be connected to the pacemaker device, which is then implanted under the skin, usually just below the collarbone.

While pacemaker implantation is generally safe, there are potential risks, including:

  • Infection at the implantation site
  • Bleeding or bruising
  • Allergic reactions to medications or materials used during the procedure
  • Damage to blood vessels or surrounding structures
  • Rarely, more serious complications such as pneumothorax (collapsed lung) or heart perforation.


Your Specialist will take precautions to minimise these risks and monitor you closely for any complications.

After the pacemaker implantation, you will be monitored in a recovery area to ensure your stability. You may experience some discomfort or swelling at the implantation site, which can be managed with pain medication.

Your Specialist will provide instructions on caring for the implantation site and restrictions on activities, such as avoiding heavy lifting for a period. You’ll also be given information on how to monitor your pacemaker at home and when to follow up with your healthcare provider for device checks.

It’s essential to attend all follow-up appointments as scheduled to ensure the pacemaker is functioning correctly and to address any concerns or issues that may arise. With proper care and monitoring, a pacemaker can significantly improve your quality of life by regulating your heart rhythm effectively.
