Exercise ECG may unmask repolarization abnormalities in moderate pediatric aortic stenosis; hypothesis-generating for risk stratification and needs prospective validation.
Does exercise stress testing unmask ventricular re-polarisation abnormalities in children with asymptomatic moderate congenital aortic valve stenosis compared to healthy controls?
Exercise stress testing unmasks ventricular repolarization abnormalities (prolonged QTc) in asymptomatic children with moderate aortic valve stenosis, which may aid in risk stratification.
