sequelae, cardiomyopathy, and congenital or valvular heart disease. No structural …

This review outlines our current understanding and approach to the clinical diagnosis and
management of LQT as well as recent insights into genotype–phenotype correlations …

Background—Genetic testing can diagnose long-QT syndrome (LQTS) in asymptomatic
relatives of patients with an identified mutation; however, it is costly and subject to …

BACKGROUND: Nearly 40% of patients with long QT syndrome (LQTS) can have a
