Heart procedure
Pacemaker Implant
A pacemaker is a small device implanted under the skin to send electrical signals that keep the heart beating at a normal rate.
Quick answer
Pacemaker Implant: what it is, why it's done and what happens
A pacemaker is a small battery-powered device placed under the skin near the collarbone, with thin wires (leads) to the heart. It monitors the heartbeat and delivers electrical impulses if the heart beats too slowly.
- Why it is done: It is used for a slow or unreliable heart rhythm causing symptoms such as dizziness, fainting, tiredness or breathlessness, and for certain problems with the heart’s electrical conduction system.
- What happens: Usually under local anaesthetic with sedation, the device is placed under the skin and the leads are guided into the heart through a vein under X-ray guidance.
What it is
A pacemaker is a small battery-powered device placed under the skin near the collarbone, with thin wires (leads) to the heart. It monitors the heartbeat and delivers electrical impulses if the heart beats too slowly.
Why it is done
It is used for a slow or unreliable heart rhythm causing symptoms such as dizziness, fainting, tiredness or breathlessness, and for certain problems with the heart’s electrical conduction system.
What happens
Usually under local anaesthetic with sedation, the device is placed under the skin and the leads are guided into the heart through a vein under X-ray guidance. It typically takes about an hour, often as a day case.
Recovery
The arm on that side is rested from heavy lifting for a few weeks while the leads settle. Most people return to normal activities quickly, with regular check-ups to monitor the device and battery.
Good to know
Risks and things to consider
Risks are small and include bleeding or bruising, infection, lead displacement and, rarely, a collapsed lung. The battery lasts several years and is replaced in a minor procedure.

Answers
Pacemaker Implant: frequently asked questions
How long does a pacemaker battery last?
Most pacemaker batteries last several years, often around 7 to 10, after which the device (not the leads) is replaced in a straightforward minor procedure.
Can I use a mobile phone or go through airport security?
Yes, with simple precautions. Keep phones away from the device and mention your pacemaker at airport security. You will be given a card and specific advice about equipment to be cautious with.
