Frontal QRS-T Angle and the Risk of Atrial Fibrillation in the Elderly

摘要

BackgroundFrontal QRS-T angle reflects changes in regional action potential duration and the direction of repolarization. Although it has been suggested that abnormal ventricular repolarization predisposes to atrial arrhythmias, it is unknown whether abnormal frontal QRS-T angle is associated with an increased risk of atrial fibrillation (AF).
