As a subject matter expert in medical devices, I can provide you with information on the longevity of batteries in Implantable Cardioverter Defibrillators (ICDs).

ICDs are sophisticated devices that continuously monitor the heart's rhythm and deliver treatment when necessary to prevent life-threatening arrhythmias. The battery life of an ICD can vary depending on several factors, including the device's age, the frequency of therapies delivered, and the specific model of the ICD.

Generally, ICD batteries are designed to last between 3 to 5 years, but this is a general estimate. Some modern ICDs may have batteries that last up to 7 years or more, especially if they are programmed to operate in a more energy-efficient mode. However, it's important to note that the battery life can be shortened if the device needs to deliver frequent therapies.

Patients with ICDs are typically seen regularly for device checks, which include monitoring the battery status. When the battery approaches the end of its expected lifespan, the ICD will alert the patient and the healthcare provider, and the device will need to be replaced.

Battery life. The lithium battery in your ICD can last up to seven years. The battery will be checked during regular checkups, which should occur every three to six months. When the battery is nearly out of power, your old shock generator is replaced with a new one during a minor outpatient procedure.read more >>
