AVJ normalized velocity-versus-time plot. Derived from the AVJ normalized displacement-versus-time plot (dotted), the AVJ normalized velocity-versus-time plot (blue) shows the calculated AVJ motion variables MVED and VDS, as indicated. The motion tracking program directly calculates the MD from the AVJ normalized displacement-versus-time plot. AVJ = atrioventricular junction; MD = maximum displacement; MVED = maximum velocity early diastole; VDS = velocity diastasis.
