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.
