Indices of mechanical dyssynchrony. Panels 1, 2, and 3 demonstrate the various indices of dyssynchrony estimated using CMR-FT. These measures were calculated for all six indices of deformation albeit only circumferential strain is shown as an example in box 1. CMR-FT, cardiac magnetic resonance-feature tracking; BAD1, base-to-apex delay using basal and apical slices; BAD2, base-to-apex delay using basal 2 and apical 2 slices
