Herein, we describe a patient with concealed type 2 long QT syndrome with concomitant electroencephalogramdocumented epilepsy. Although syncope in patients with long QT syndrome is common and often secondary to cerebral hypoxia after a protracted ventricular arrhythmia, this article demonstrates the importance of avoiding "tunnel vision" as patients with long QT syndrome could also have a primary seizure disorder. Identification of the etiology underlying seizurelike activity is paramount in instituting effective therapy. Furthermore, we theorize that abnormal KCHN2- encoded potassium channel repolarization in the brain could result in epilepsy and arrhythmias in long QT syndrome.
