AbstractLong QT syndrome patients can present as second-degree AV block due to prolongation of refractory period. We report a case of pseudo 2:1 AV block due to long QT syndrome in which treatment differs from conventional second-degree AV block because of uncommon presentation and poor prognosis with no consensus.

We report a case of 2:1 atrioventricular block associated with acquired long QT syndrome. A newborn presented to our neonatal intensive care unit with intermittent bradycardia due to 2:1 atrioventricular block. Initial evaluation showed QT prolongation and significant electrolytic abnormalities. After correction of the electrolytic imbalance, the QT interval normalized and atrioventricular block resolved. Compared to congenital long QT syndrome with 2:1 atrioventricular block, acquired long QT syndrome with comparable atrioventricular block has a benign prognosis, provided treatment is initiated quickly.
