Short QT syndrome
Multiple genes have been implicated in the syndrome including KCNH2, KCNQ1, and KCNJ2. These genes code for cardiac ion channels.
Many patients with short QT syndrome receive cardioverter-defibrillator implantation. Antiarrhythmic drugs are sometimes used, but there is incomplete evidence for their effectiveness.
