Factor traversals of a subset of the electrocardiogram factors for Leads I, II, V1, V3, V6. Factor traversals of a subset of the 21 electrocardiogram factors that hold significant information for correctly reconstructing electrocardiograms. Each row corresponds to the factor traversal for one electrocardiogram factor and the columns to a subset of the 12 leads. The factor traversal for one row is obtained by starting with a ‘mean’ FactorECG where all factors are zero and adding offsets for that factor in a range of −5 to 5. The generated electrocardiograms are then plotted where red represents high values for that factor and blue low values.
