Table 1 Mean intensity values for radial motion of one normal subject and two patients, one of Group1 and one of Group2, before and after CRT. Values presented for the walls depicted in Figure 1—anterior, inferior, septal, and lateral—for the LV midcavity portion. The computed intensity values are mapped to a scale that allows a maximum of and a correspondent minimum of .
