Figure 1 Segmentation schemes used for analysis of endocardial wall motion (see text). (A) Short-axis view (SAX): ant = anterior, asp = anteroseptal, sp = septal, inf = inferior, pst = posterior, lat = lateral. (B) apical four-chamber view (A4C): b-lt = basal lateral, m-lt = mid-lateral, a-lt = apical-lateral, a-sp = apical-septal, m-sp = mid-septal, b-sp = basal-septal. (C) Apical two-chamber view (A2C): b-an = basal-anterior, m-an = mid-anterior, a-an = apical-anterior, a-in = apical-inferior, m-in = mid-inferior, b-in = basal-inferior. (D) Parasternal long axis view: b-asp = basal anteroseptal, m-asp = mid-anteroseptal, m-pst = mid-posterior, b-pst = basal posterior.
