HA classification of fiber tracts passing through a ROI placed in the lateral wall of the LV (A) . The tracts have been limited in length to half the LV circumference (Ï€R). Tracts in the lateral wall of normal human (B-D) normal sheep (E-G) and normal rat hearts (H-J) are shown. The discrete HA maps (B, E, H) show that HA is highest in the midventricular portion of a given myofiber and decreases as the fiber approaches either the base or the apex. Only a slight reduction in HA range is produced by median HA classification (C, F, I). The reduction in HA range with mean HA classification (D, G, J) is slightly larger.
