Description
Prolonged QT interval syndrome, also known as “congenital long QT syndrome (LQTS),” is characterized by prolongation of the QT interval on the surface ECG, syncope, and sudden death as a result of malignant ventricular arrhythmias. The electrical instability is due to an abnormality of ventricular repolarization associated with a cardiac ion channelopathy.
