LVAMs LV short axis are at mitral value at end systole Refer to Section 8.4.1.2
Area and Circumference
The system automatically calculates the following items according to the measurenment results.
Calculation Item Description Formula
EDV End- diastolic Left
Ventricular Volume
EDV(ml)=(5/6/ ) × LVLd( ) × LVAMd( )
ESV End- systolic Left
Ventricular Volume
ESV(ml)=( 5/6/ ) × LVLs( ) × LVAMs( )
SV Stroke Volume SV = EDV(ml) - ESV(ml)
EF Ejection Fraction EF=100% × SV(ml)/EDV(ml)
SI Stroke Volume Index SI=SV(ml)/BSA( )
CO Cardiac Output CO(l/min)=SV(ml) × HR(bpm)/1000
CI Cardiac Index CI=CO(l/min)/BSA( )
Mod.Simpson
This measurement method calculates the LV volume by using the LV long axis view, the LV short axis at
the level of the mitral value and the LV short axis view at level of the papillary muscles.
Steps:
1. Press the Measure key in the real time or frozen B/Color/PDI mode, and the measurement menu
displays on the top left of the screen.
2. Select [LV] on the menu by moving the trackball and press Set to confirm.
3. Select [Mod.Simpson] on the pop-up menu and a marker displays on the image.
4. Perform the LVLd LVLs LVAMd LVAMs LVAPd LVAPs measurements one by one and the
measurement results displays in the result box.
