Careful ICD reprogramming can successfully eliminate T-wave oversensing and inappropriate shocks in patients with short QT syndrome.
Individualized ICD reprogramming may reduce inappropriate shocks in short QT syndrome; hypothesis-generating pending prospective validation.
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.

Sun et al. (2009) conducted a case report in Short QT syndrome (n=1). ICD reprogramming was evaluated on T-wave oversensing and inappropriate discharge. Reprogramming of a dual-chamber ICD successfully eliminated frequent T-wave oversensing and inappropriate discharges in a patient with short QT syndrome over a 6-month follow-up.
