Long QT syndrome (LQTS) is an uncommon cardiac disorder of repolarisation leading to
prolonged QT interval and T wave abnormalities in the ECG, thus predisposing to Torsades …

2: 1 AV Block in LQTS. Introduction Conduction abnormalities associated with long QT
syndrome (LQTS) have been reported as “pseudo 2: 1 AV block” due to sinus intervals …

Figure 1. Electrocardiographic traces from leads II and V5 (A, C–F) and lead II (B) in patients

Long QT syndrome (LQTS) can be asymptomatic-identifiable as an incidental finding on
electrocardiogram-or it can present with palpitation, syncope, seizures, or sudden cardiac …

A 16 year-old asymptomatic male was diagnosed with long QT syndrome (LQTS) at age 7
due to family history and an abnormal electrocardiogram. Genetic testing confirmed the …

Long QT syndrome (LQTS) is linked to mutations in the ion channels, which can lead to
disturbances in ventricular repolarization [1]. This condition puts patients at risk for syncope …

Since the early description of its phenotypes, 1–3 congenital long QT syndrome (LQTS) has
been recognized as a disease entity showing prolonged QT intervals on electrocardiogram …

Pseudo 2: 1 AV block when sinus intervals are shorter than the ventricular refractory period
has been reported with long QT syndrome (LQTS). We report the characteristics and …
