How do you know when to change a pacemaker battery?

A pacemaker battery typically needs to be changed when the device's monitoring system indicates that the battery is low or nearing its end of life, usually within 6 to 12 months before depletion. Patients may also experience symptoms such as fatigue, palpitations, or other irregular heart sensations if the battery is failing. Regular follow-up appointments with a healthcare provider, where the device's function and battery status are checked, are essential for timely replacements. It’s crucial to adhere to scheduled evaluations to ensure optimal heart function and device performance.
