Abstract:
Accurate sensing is an essential requirement for appropriate functioning of implantable cardioverter-defibrillator (ICD). T-wave oversensing remains as an annoying problem in currently available ICD. The Brugada syndrome with its inherent dynamic variations in electrophysiologic phenomena may complicate ICD therapy. We report a patient with diagnosis of Brugada syndrome who presented with frequent inappropriate therapy due to intermittent T-wave oversensing. This problem could not be eliminated by device reprogramming and necessitated implantation of a new sense/pace lead.
