Long QT syndrome (LQTS) is a rare inherited cardiac condition characterized by QT prolongation and T-wave abnormalities on the electrocardiogram (ECG). It is com­monly associated with syncope, however, sudden car­diac death can occur due to Torsades de Pointes (TdP). We report the case of a 27-year-old female patient with genetically confirmed LQTS type 2 KCNH2 gene mu­tation found, who experienced multiple syncopes since a young age. After antipsychotic drugs were removed and ß-adrenoblockers were prescribed, fainting episo­des did not reoccur.
