Inappropriate ICD discharge due to T-wave oversensing in a patient with short QT syndrome.
A 45-year-old man with diagnosis of short QT syndrome underwent successful implantation of dual-chamber implantable cardioverter-defibrillator (ICD) to prevent sudden cardiac death. Ten days after implantation, the patient was treated by inappropriate ICD discharges for frequent T-wave oversensing. After careful reprogramming of the ICD, the T-wave oversensing was eliminated and no T-wave oversensing or inappropriate discharge was documented during 6-month follow-up period.
