Mexiletine infusion challenge test for neonatal long QT syndrome with 2:1 atrioventricular block
Abstract For applying a genotype‐based treatment in neonatal long QT syndrome (LQTS), early detection of the genotype becomes an important issue. We report a case of a neonate with LQTS type 3 that presented with 2:1 atrioventricular block and underwent a mexiletine infusion challenge test, and achi...

description | Abstract For applying a genotype‐based treatment in neonatal long QT syndrome (LQTS), early detection of the genotype becomes an important issue. We report a case of a neonate with LQTS type 3 that presented with 2:1 atrioventricular block and underwent a mexiletine infusion challenge test, and achieved shortening of the QTc and 1:1 atrioventricular conduction. The mexiletine infusion challenge test was helpful to make an early detection of the genotype of the LQTS and predicted the drug efficacy in a neonatal patient. |
