The '''Long QT Syndrome (LQTS)''' is characterized on the ECG by prolongation of the [[Conduction#The_QT_interval|heart rate corrected QT interval]]. This was first recognized by Dr. Jervell and Dr. Lange-Nielsen in 1957. They described 4 children with a long QT interval which was accompanied by hearing deficits, sudden cardiac death and an autosomal recessive inheritance.<cite>Lang1957</cite> | The '''Long QT Syndrome (LQTS)''' is characterized on the ECG by prolongation of the [[Conduction#The_QT_interval|heart rate corrected QT interval]].
