Web6 de out. de 2024 · Long QT syndrome (LQTS) is characterized by a 12-lead ECG pattern showing a prolonged QT interval that can progress to a polymorphic ventricular tachycardia (VT) known as torsades de pointes (TdP). Fig. 2 shows the ECG obtained in a 26-year-old resuscitated woman with LQTS (genotype-undetermined). WebAbstract. Congenital long QT syndrome (LQTS) encompasses a group of heritable conditions that are associated with cardiac repolarization dysfunction. Since its initial description in 1957, our understanding of LQTS has increased dramatically. The prevalence of LQTS is estimated to be ∼1:2,000, with a slight female predominance.
