A 75-year-old woman with a dual-chamber pacemaker was seen in the cardiology clinic for possible device malfunction. The patient’s device identification card revealed that a pacemaker from “Manufacturer A” was implanted in 2001. However, device interrogation using the corresponding programmer failed to communicate with the device. Given the age of the device, complete depletion of the battery was suspected and the patient was thus referred for pacemaker generator change.
