Example of fagmented QRS. The different morphologies of fQRS are shown in this figure; notching of the R wave in leads II, III, and aVF, and notching in nadir of the S wave in leads I, aVL. The quantitative fQRS (Q-fQRS) counting is indicated by red arrows. Each arrow represents a positive or negative deflflection counted as fractionated signal. Lead I, AVL, II, III, AVF have a Q-fQRS count being 4, 4,3, 4 and 5, respectively. The total Q-fQRS count in this figure add up to 20
