Quick read
Key points
- 1
A pacemaker is a small device implanted under the skin, usually near the collarbone, to help control an abnormal heart rhythm. It sends electrical signals to the heart to help it beat at a steady, appropriate rate when its natural rhythm is too slow or irregular.

What is Pacemaker?
A pacemaker is a small device implanted under the skin, usually near the collarbone, to help control an abnormal heart rhythm. It sends electrical signals to the heart to help it beat at a steady, appropriate rate when its natural rhythm is too slow or irregular.
Pacemakers are commonly fitted for conditions such as a slow heart rate (bradycardia) or certain types of heart block, and the procedure to fit one is usually done under local anaesthetic and takes about an hour.

Clinical context
Self-care advice
Your cardiac team will schedule regular checks, sometimes remotely, to monitor your pacemaker's function and battery life.
03 · Act
When to see a doctor
- 1You notice swelling, redness, or discharge around the pacemaker site after implantation
- 2You experience dizziness, fainting, or palpitations after having a pacemaker fitted
- 3You have hiccups that won't stop, which can occasionally indicate the pacemaker lead needs checking
- 4You're due a routine pacemaker check and haven't yet booked it
- 5You're unsure whether a piece of equipment or medical procedure is safe with your pacemaker

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Attend all follow-up checks.Pacemakers are monitored regularly to check the battery and settings are working correctly.
- 2Carry your pacemaker ID card.This lets other healthcare providers and airport security know you have a device fitted.
- 3Avoid strong magnetic fields where advised.Certain equipment can interfere with pacemakers, so always mention your device before medical scans or procedures.
- 4Keep the wound clean after fitting.Follow your care team's instructions on caring for the incision site while it heals.
- 5Ease back into activity gradually.Most people can return to normal activities within a few weeks, following guidance from their cardiac team.

BarnMD Bottom Line
A pacemaker can significantly improve quality of life and symptoms for people with slow or irregular heart rhythms, with most people adjusting to it quickly.
Regular pacemaker checks ensure the device continues to work exactly as it should for years to come.
