Abstract excerpt

BACKGROUND: LQT1 subtype of long QT syndrome is characterized by defective I(Ks) , which is intrinsically stronger in the epicardium than in the midmyocardial region. Electrocardiographic QT peak and QT end intervals may reflect complete repolarization of epicardium and midmyocardial region of the ventricular wall, respectively. Repolarization abnormalities in LQT1 carriers may therefore be more easily detected...
