Short QT syndrome (SQTS) is a cardiovascular disorder resulting from mutations in cardiac ion channels. The mutation of genes (KCNH2, KCNQ1, and KCNJ2) encoding for cardiac potassium channels plays a central role in SQTS. SQTS is characterized by constantly short QT interval associated with atrial fibrillation, syncopal episodes, and sudden cardiac death. The implantable cardioverter defibrillator (ICD) therapy in patients with a short QT syndrome has an increased risk due to possible T wave oversensing.
