Figure 9-4 Height and Weight Input Dialog Box
2. Input suitable values in the Height and Weight boxes.
3. Roll the trackball to highlight OK and press Set.
The measurements and calculations of all the LV parameters are as below.
Measurement or input items:
Input or measurement items: HR, LVET, and Height & Weight;
Measurement items: LVIDd and LVIDs
To calculate all the LV parameters:
1. Input or measure HR, LVET, and Height & Weight.
2. Measure LVIDd and LVIDs following the prompt instruction.
3. All the LV parameters, EDV, ESV, SV, FS, EF, CO, MVCF, SI and CI will be displayed in the
measurement result window.
9.1.2. Mitral Valve
Measurement items of mitral valve include EF slope, ACV, A/E, DEV, and DCT.
To measure EF slope, ACV, and A/E
1. In the M-cardiac measurement menu, roll the trackball to highlight Mitral Valve to display
the submenu.
2. Roll the trackball to highlight EF Slope, ACV, or A/E, and press Set.
a) To measure EF Slope and ACV, by the method of generic M mode slope measurement;
b) To measure A/E, measure the breadth from apex A to point C and the breadth from apex
E to point C respectively, by the method of generic M mode distance measurement.
3. After the measurements, the results of EF SLP, ACV and A/E will be displayed in the
measurement result window.
To measure Valve Volume (QMV)
Calculation formula:
QMV (mL) = 4*DEV (cm/s)*DCT (s)
