Ventricular Mass
See LV Mass-I formula in “Left Ventricular Mass (LV
Mass)”
 Operating Procedures
1. Select [LV Mass (Cube)] in the measurement menu.
2. At end diastole, measure the following parameters:
IVSd
LVIDd
LVPWd
The LV Mass (Cube) is calculated.
If height and weight have been input already, LV Mass-I(Cube) is calculated.

 Operating Procedures
1. Select [LV Mass (A-L)] in the measurement menu.
2. In long-axis view at end diastole, measure LVLd apical；
3. In short-axis view at papillary muscle level at end diastole, measure the following parameters:
Endocardium area: LVAd sax Endo;
Epicardium area: LVAd sax Epi
