Published in: Pacing and clinical electrophysiology : PACE (2021)

A retrospective analysis of 60 patients with hybrid implantable cardioverter-defibrilator (ICD) systems: Boston Scientific device paired with non-Boston leads. In 10 (17%) patients transient, out-of-range peaks of ventricular pace impedance trend were observed. Probable cause is header-lead interaction incompatibility. This matter is known mainly for pacemakers systems but not for ICDs. Investigation this issue is crucial because consequences in ICD systems are unpredictable and risk might be higher than in pacing systems.
