Abstract excerpt

Aims: QT prolongation during mental stress test (MST) has been associated with familial idiopathic ventricular fibrillation. In long QT syndrome (LQTS), up to 30% of mutation carriers have normal QT duration. Our aim was to assess the QT response during MST, and its accuracy in the diagnosis of concealed LQTS. Methods and results: All patients who are carrier of a KCNQ1 or KCNH2 mutations without QT prolongation...
