Figure 2 Recordings of velocity–time curves by pulsed tissue Doppler imaging from the basal septum and lateral wall, as indicated in the scheme of the apical four-chamber view measuring systolic (S′), early diastolic (E′), and atrial (A′) myocardial velocity. Global left ventricular function is calculated as the average of these regional segmental velocities. LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle [8].
