Activation maps for patient 2 (septal implant) at each pacing modality. Top row: Activation time maps. The red and blue areas indicate early and late activation. Bottom row: Unipolar electrograms for 1 LV and 1 RV location are indicated in pink on the activation maps above. The dots on the electrograms indicate the annotated activation times. BiV = biventricular; BIVAT-90 = time for 90% biventricular activation; BiVDI = biventricular dyssynchrony index; LV, left ventricular; LVAT95 = time for 95% left ventricular activation; LVDI = left ventricular dyssynchrony index; RVAT90 = time for 90% right ventricular activation.
