Figure 1 Myocardial Wall Motion in a Control Subject and in a Patient With Heart Failure
(A) Division of the left ventricular (LV) myocardium into slices and segments. (B) The junction between the interventricular septum and the right ventricular (RV) free wall delimits the beginning of segment 1 and the end of segment 6, counting clockwise. (C and D) Representative graph of radial wall motion of LV segments throughout the cardiac cycle in an LV basal slice in a control subject (C) and in a patient with heart failure (HF) and a left bundle branch block (LBBB) (D).
