Infants with congenital long QT syndrome (LQTS) and 2:1 atrioventricular block (AVB) have been recognized as a clinical subset of children with LQTS. However, the genotype of this disorder is not well-known. We report an infant with LQTS and 2:1 AVB with a mutation of the SCN5A gene (LQT3). In some patients with LQTS and 2:1 AVB, the disorder may be due to mutation of the SCN5A gene (LQT3).
