(A) Profiles of apical segmental and global (dotted line) rotational rate (Vrot) (°/sec) in a 6 month-old normal boy. LV apex showed systolic counterclockwise (positive) Vrot and clockwise early diastolic (negative) Vrot. (B) Profiles of apical segmental and global (dotted line) rotational rate (Vrot) (°/sec) in a 6 month-old boy with DCM. Systolic counterclockwise Vrot and early diastolic clockwise Vrot were abolished. Considerable rotational heterogeneity was noticed particularly at the apical level.
