As a biomedical engineer with expertise in medical devices, I can provide you with information on the typical battery life of a pacemaker.
Pacemakers are designed to be quite durable and reliable, with battery life being a critical consideration. The longevity of a pacemaker's battery can vary depending on several factors, including the specific model, the patient's unique heart condition, and how often the device needs to deliver therapy.
Generally, a pacemaker's battery is expected to last between 5 to 10 years, with an average lifespan of around 7 years. However, some modern pacemakers with more efficient power management may last even longer. It's important to note that the battery life can be influenced by the amount of pacing the heart requires. For instance, if the pacemaker is pacing more frequently or if the patient has a more active lifestyle, the battery may need to be replaced sooner.
Patients with a pacemaker are typically monitored regularly to assess the battery's status. When the battery approaches the end of its life, the pacemaker may start to send signals that it's time for a replacement, and a minor surgical procedure can replace the battery or the entire device, depending on the specific situation.
