Also called a device check or device follow-up. A routine clinic appointment (or remote session via home monitoring equipment) in which a clinician uses a programmer — a handheld device held over your chest — to wirelessly communicate with your ICD or pacemaker. The interrogation reads stored data including any arrhythmia episodes, shocks delivered, battery status, and lead performance. Most patients with an ICD have a formal in-person interrogation at least once a year, supplemented by remote monitoring between visits.
