Methodology for measuring time of exceeding aortic valve closure contraction. The sum of the time of strain tracing exceeding aortic valve closure (ExcT) is calculated on the 12 LV basal and middle segments in the standard apical views. AVO = aortic valve opening, AVC = aortic valve closure(Modified from Porciani MT et al, Eur Heart J 2006;27:1818–1823)
