Long QT syndrome 2 (LQT2) is a hereditary disorder characterized by abnormal prolongation of the QT interval on the electrocardiogram and an increased risk of life-threatening ventricular arrhythmias, such as torsades de pointes. This condition is caused by impaired repolarization of the ventricular myocardium, which leads to an increase in the duration of the action potential of cardiomyocytes. The development of the syndrome at a young age is especially dangerous, when the first manifestation of the disease may be sudden cardiac death.<\/p>\n
