Update of Diagnosis and Management of Inherited Cardiac Arrhythmias
Key result
Genetic studies have identified 13 forms of congenital LQTS in 50-80% of clinically affected patients, whereas only one-third of Brugada syndrome patients can be genotyped, guiding genotype-specific management.

Implication
Updated LQTS and BrS diagnostic criteria should inform immediate clinical decisions; extends genetic classification to 13 forms.

Population
Patients with inherited cardiac arrhythmias, specifically congenital long QT syndrome (LQTS) and Brugada syndrome (BrS)
Advances in genetic testing and genotype-phenotype correlations are increasingly informing the diagnosis and genotype-specific management of inherited cardiac arrhythmias.
Limitations
- The precise prevalence of the LQTS genotype is unknown because all 13 responsible genes are not routinely screened in clinical practice.
- Approximately two-thirds of clinically diagnosed Brugada syndrome patients have not yet been genotyped.
Cite This Study
Wataru Shimizu (2013) conducted a review in Inherited Cardiac Arrhythmias (Congenital Long QT Syndrome and Brugada Syndrome). Genetic testing and genotype-specific management was evaluated. Genetic studies have identified 13 forms of congenital LQTS in 50-80% of clinically affected patients, whereas only one-third of Brugada syndrome patients can be genotyped, guiding genotype-specific management.
