Flow propagation velocity echo
WebFeb 1, 2000 · Flow propagation velocity was measured as the slope of the first color aliasing velocity (45 cm/s) from the mitral annulus in early diastole to 4 cm distally into the LV cavity (Fig. 1). In patients with low peak E-wave velocity where no color aliasing was seen, baseline shift was adjusted to aliase at about 75% of the peak E-wave velocity. WebAs per the ASE: "Color M-mode measurements of the early diastolic flow propagation velocity from the MV to the apex correlate well with t and provide another means by which to evaluate LV filling; as LV relaxation becomes abnormal, ... If M-mode not obtained during echocardiography, one may use the FAC tracing and connect the hinge point of the ...
