Long QT syndrome

MONDO:0002442

A condition that is characterized by episodes of fainting (syncope) and varying degree of ventricular arrhythmia as indicated by the prolonged QT interval. The inherited forms are caused by mutation of genes encoding cardiac ion channel proteins. The two major forms are Romano-Ward syndrome (also known as long QT syndrome 1) and Jervell-Lange Nielsen syndrome.

Also known as: long QT syndrome, ventricular arrhythmia associated with long QT syndrome
