Figure 6 Time Sequence Analysis of LV Flow During 1 Cardiac Cycle in Abnormal LV Systolic Function Group

The vortex was located at the center of the LV throughout diastole and systole and did not redirect flow in a coherent, sequential fashion as in normal subjects. Early ejection: 16 ms after aortic valve opening (A); late ejection: 138 ms after aortic valve opening (B); IVR-1: 32 ms after aortic valve closure (C); IVR-2: 50 ms after aortic valve closure (D); early diastole: 32 ms after mitral valve opening (E); diastasis: 124 ms after mitral valve opening (F); late diastole: 245 ms after mitral valve opening (G); isovolumic contraction period (IVC): 64 ms after mitral valve closure (H).
