Figure 2 Digital Particle Image Velocimetry Profiles of LV Flow During Phases of Cardiac Cycle

For each phase, the local ensemble-averaged axis-normal velocity magnitude (Vel Mag) is superimposed on the vector field. (A) Pre-ejection. (B) Ejection. (C) Isovolumic relaxation. (D) Early diastole. (E) Diastasis. (F) Late diastole. LA = left atrium; LV = left ventricle.
