Pacemaker Implantation

Published with the inputs from Dr John F John, Cardiologist, Baby Memorial Hospitals- Kozhikode

A pacemaker is a small medical device implanted under the skin of the chest to help regulate abnormal heart rhythms (arrhythmias). It sends electrical signals to the heart to maintain a normal heartbeat. Pacemaker implantation is a common and safe procedure that improves quality of life and reduces the risk of complications from slow or irregular heartbeats.

What is a pacemaker, and why is it needed?

A pacemaker is an electronic device that regulates the heartbeat. It is recommended for patients with:

• Slow heart rate (bradycardia)
• Heart block (disrupted electrical signals in the heart)
• Certain types of arrhythmias causing dizziness, fatigue, or fainting

How is pacemaker implantation performed?

• The procedure is usually done under local anesthesia with sedation.
• A small incision is made near the collarbone.
• The pacemaker leads (wires) are guided into the heart through a vein and connected to the device.
• The device is placed under the skin of the chest.
• The procedure typically takes 1–2 hours.

Is pacemaker implantation safe?

Yes. It is a routine and safe procedure. Risks like infection, bleeding, or lead displacement are rare and minimized with expert care.

What is recovery like after pacemaker surgery?

• Most patients go home within 24–48 hours.
• Mild soreness at the incision site for a few days is common.
• Normal activities resume in 1–2 weeks, but strenuous activities should be avoided initially.
• The pacemaker is regularly checked and programmed to suit the patient’s needs.

Can I live normally with a pacemaker?

Yes. Patients can lead normal, active lives with a pacemaker.

• Avoid prolonged exposure to strong magnetic/electrical fields.
• Regular follow-ups are needed to check device function.

Most pacemakers last 8–12 years before replacement is required.

What lifestyle changes are needed with a pacemaker?

• Take heart medications as prescribed.
• Stay active with doctor-approved exercises.
• Avoid smoking and excessive alcohol.
• Maintain regular cardiology follow-ups.
