          Abstract

          Inappropriate delivery of therapy due to T-wave oversensing is a frequent complication of intracardiac cardioverter defibrillators (ICD). A 16-year-old adolescent with congenital long QT syndrome type 3 underwent single-chamber implantable cardioverter defibrillator (ICD) (EnTrust VR, Medtronic Inc., Minneapolis, MN, USA) implantation.He received two appropriate and four inappropriate shocks. The inappropriate shocks were due to T-wave oversensing. Following the replacement of ICD with a different brand generator (Vitality 2 VR, Boston Scientific Inc., Natick, MA, USA), no more T-wave oversensing is noted. Proper filtering is imperative in ICDs in order to prevent T-wave oversensing-related inappropriate delivery of therapy.
