AbstractBackground: Transient loss of consciousness may be due to cardiac cause. Arrhythmias may lead to syncope or to sudden death. Long QT syndrome (LQTS) is a genetically transmitted cardiac arrhythmia caused by ion channel protein abnormalities. It is characterized by electrocardiographic abnormalities and a high incidence of sudden cardiac death. Case Report: We report a case of long QT syndrome in a 10-year girl child who was treated for refractory seizures with multiple antiepileptic drugs. Simple electrocardiography confirmed the diagnosis. Conclusion: Child was treated with non-selective beta blocker and showed dramatic response.
