How are pacemakers maintained?

Pacemaker followup: Pacemakers are followed by cardiologists in two ways--they are seen regularly in the office to adjust and check the battery. In between office visits the devices can be checked remotely either over the phone or internet.

Regular checks: Patients with pacemakers must see their cardiologist regularly or have remote monitoring of their implanted device. In both cases, the device is interrogated with a programmer. The programmer can be use to adjust the settings per the instructions of the cardiologist. The interrogation also predicts battery life so that generator exchange can be scheduled before the device end of life.
