Why the study?
Congenital long QT syndrome is heterogeneous, and effective therapy requires molecular genetic diagnosis to accurately determine the type of pathology.
This review highlights the clinical and genetic heterogeneity of congenital long QT syndrome and the importance of molecular genetic diagnosis for guiding effective therapy.

Supports genotype-guided therapy in congenital LQTS; leaves open the need for prospective validation studies.
Long QT syndrome is a rare ion channel cardiac disorder, the main manifestations of which are prolongation of the QT interval on the ECG and ventricular arrhythmias, which can cause sudden cardiac death at a young age. Diagnosis and treatment of this syndrome is an urgent problem, since the disease is heterogeneous and effective therapy requires molecular genetic diagnosis to accurately determine the type of this pathology. This review discusses clinical and genetic characteristics of different types of congenital long QT syndrome.
