Time shift of marker legend in stored intracardiac events in three patients with the vitality 2 EL DR (model T167) and Prizm 2DR (model 1861) dual-chamber defibrillators.
With the increase in complexity of implantable cardioverter defibrillators (ICD), the reliability of these devices has been put in question in recent years. We report on 3 patients implanted with the Boston Scientific Vitality 2 EL DR (n = 2) and the Prizm 2 DR (n = 1) ICD who exhibited a malfunction in the stored cardiac electrograms from arrhythmic events, manifesting as a time shift in stored markers compared to the stored electrograms.
