Answer

Patients with ICDs require regular outpatient device follow-up to allow monitoring of battery and transvenous lead status. Although battery lifetime is somewhat predictable, lead fracture and failure may occur at any time. Lead problems can generally be diagnosed in the clinic and occasionally necessitate lead revision or replacement.

In addition, the efficacy of the ICD should be rechecked after the initiation of medications that may increase the ventricular defibrillation threshold. This is typically accomplished by means of an outpatient noninvasive programmed stimulation study (NIPS) carried out through the implanted device.
