Long QT syndrome (LQTS) is a rare cardiac channelopathy associated with syncope
and sudden death due to torsades de pointes and ventricular fibrillation. Syncope
and sudden death are frequently associated with physical and emotional stress.
Management of patients with LQTS consists of life-style modification, ?-blockers,
left cardiac sympathetic denervation (LCSD), and implantable
cardioverter-defibrillator (ICD) implantation. Prohibition of competitive
exercise and avoidance of QT-prolonging drugs are important issues in life-style
modification. Although ?-blockers are the primary treatment modality for patients
with LQTS, these drugs are not completely effective in some patients. Lifelong
ICD implantation in young and active patients is associated with significant
complications. LCSD is a relatively simple and highly effective surgical
procedure. However, LCSD is rarely used.
