Figure 4 Time-Resolved Left Ventricular Flow During the Isovolumic Relaxation Phase
(A) Anatomical M-mode through the left ventricle (LV). (B) Two-dimensional snapshots of 3 time frames shown by vertical lines
(1 to 3) in panel A. 1 and 2, the initial flow after ejection is reversed toward the apex. This is followed by a brief reversal of the flow toward the LV base (3). HR = heart rate; LA = left atrium; Vel Mag = velocity magnitude.
