Abstract excerpt

AIMS: We aimed to examine the validity of heart rate (HR) at rest before β-blocker therapy as a risk factor influencing cardiac events (ventricular fibrillation, torsades de pointes, or syncope) in long QT type 2 (LQT2) patients. METHODS AND RESULTS: In 110 genetically confirmed LQT2 patients (45...
