Jervell and Lange-Nielsen syndrome (JLNS) is a type of long QT syndrome associated with severe bilateral hearing loss. Long QT syndrome causes the cardiac muscle to take longer than usual to recharge between beats. If untreated the irregular heartbeats called arrhythmias can lead to fainting seizures or sudden death. It was first described by Anton Jervell and Fred Lange-Nielsen in 1957.
