Case Report (n=1)
Highlights the importance of accurate diagnosis of congenital long QT syndrome in pediatric patients presenting with syncope, which can be misdiagnosed as epilepsy.
The article presents a clinical case of a 16-year-old girl with clinical manifestations of congenital long QT interval syndrome in the form of syncope which were primarily diagnosed as epileptic syndrome for which the patient was taking anticonvulsant drugs having qualities of secondary prolongation of QT interval. At the same time, the data of family anamnesis (sudden death of the mother at a young age) in combination with typical manifestations of disease and electrocardiographic signs (prolonged QT interval measured from the standard electrocardiogram, paroxysms of spindle-shaped ventricular tachycardia accompanied with syncope conditions) made it possible to diagnose congenital long QT interval syndrome and implant an electric cardiac pacemaker.

Скуратова et al. (2021) conducted a case report in Congenital long QT syndrome (n=1). Implantable cardioverter-defibrillator (ICD) was evaluated on Diagnosis and clinical management. A 16-year-old girl presenting with syncope initially misdiagnosed as epilepsy was successfully diagnosed with congenital long QT syndrome and treated with an implantable cardioverter-defibrillator.
