Definition of the imaging planes and regions used in the echocardiographic imaging of the LV. (a) Long axis imaging planes. AP2: apical two-chamber view; AP3: apical three-chamber view; AP4: apical four-chamber view. (b) Short axis imaging planes. B: basal; M: mid, AP: apical. (c) Short axis imagining regions, as viewed from the base of the heart. The regions appear in opposite order to those in the apical view used in imaging. AS: anterior septal; A: anterior; AL: anterior lateral; IL: inferior lateral; I: inferior; IS: inferior septal. (d) Long axis imaging regions.
