How long can a cardiac pacemaker last?

The service life of a pacemaker is not a fixed number, but rather influenced by multiple factors. Generally speaking, the lifespan of modern pacemakers typically ranges from 5 to 15 years. The actual longevity primarily depends on parameters such as the battery capacity of the pacemaker, pacing rate, pulse amplitude and width, as well as the patient's own cardiac condition and the operating mode of the pacemaker. If a patient is highly dependent on the pacemaker and it operates frequently, battery consumption will accelerate, thereby shortening its lifespan. Ongoing advancements in pacemaker technology also affect longevity to some extent—newer models often feature improved battery performance.

If any discomfort occurs, medical attention should be sought promptly.
