Is pacemaker implantation a major surgery?
Pacemaker implantation is considered a minor to moderately invasive procedure, not a major open-heart surgery. It is typically performed under local anaesthesia with mild sedation. A small incision is made near the collarbone, the leads are guided into the heart through a vein, and the device is placed under the skin. Most patients go home within 1–2 days and recover fully within 4–6 weeks.
Modern pacemakers typically last between 5 to 15 years, depending on the model and how frequently it needs to pace your heart. Your cardiologist will monitor battery levels during routine check-ups. When the battery runs low, only the device (not the leads) usually needs to be replaced in a straightforward procedure.
Most people do not feel their pacemaker working. Occasionally, some patients may notice a slight fluttering or increased heart rate, especially during physical activity. The device is designed to work seamlessly in the background. If you feel palpitations, dizziness, or discomfort, contact your doctor — this is uncommon but worth checking.
Yes, absolutely. The vast majority of people with pacemakers lead full, active, and normal lives. You can exercise, travel, work, and enjoy daily activities. Many patients actually feel significantly better after implantation as their heart rhythm becomes stable. Your doctor will provide specific guidance based on your condition.
The battery in a pacemaker typically lasts 5 to 15 years. The exact duration depends on the type of pacemaker, how often it is pacing, and the settings programmed for your condition. During regular follow-ups (every 6–12 months), the battery status is monitored closely so replacement can be planned well in advance before it runs out.
There are a few precautions to keep in mind. You should avoid prolonged close contact with strong magnetic fields (like MRI machines — though many newer pacemakers are MRI-compatible). Keep mobile phones and earbuds at least 6 inches from the device. Avoid leaning over running engines or high-voltage equipment. Most household electronics, microwaves, and air travel are completely safe.
After implantation, you will typically have a check-up within 4–6 weeks, then every 6 to 12 months thereafter. Some pacemakers support remote monitoring, allowing your cardiologist to review device data without you needing to visit the clinic. As the battery nears end of life, appointments may become more frequent.
