E to point C respectively, in 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)
Measurement operation procedure:
1. In the M-cardiac measurement menu, roll the trackball to highlight Mitral to display the
secondary menu.
2. Roll the trackball to highlight Valve Volume, and press Set.
3. Measure DEV, in the method of generic M mode slope measurement.
4. Measure DCT, in the method of generic M mode time measurement.
5. After the measurement, the result of QMV will be displayed in the measurement result
window.
8.1.3. Aortia
Aortia calculation is as below.
z Measurement items:
LAD/ AOD and Valve Volume
z Aortia calculation
In the M-cardiac measurement menu, roll the trackball to highlight Aortia to display the
secondary menu.
 LAD/AOD measurement
1. Roll the trackball to highlight LAD/AOD and press Set.
2. Measure LAD and AOD respectively, in the method of generic M mode distance
measurement.
3. The results will be displayed in the measurement result window.
 AVSV measurement
The calculation formula:
AVSV (mL) = MAVO1 (cm)+MAVO2 (cm)*ET (s)*50+AA (cm)
The measurement operation procedure:
1. Roll the trackball to highlight Valve Volume and press Set.
2. Measure MAVO1, in the method of generic M mode distance measurement.

3. Measure MAVO2, in the method of generic M mode distance measurement.
4. Measure AA, in the method of M mode distance measurement.
5. Measure LVET, in the method of generic M mode time measurement.
6. After the measurements, the result of AVSV will be displayed in the measurement result
window.
8.1.4. LVMW, LVMWI
LVMW and LVMWI calculations are as below.
z Measurement items:
LVPWd, IVSTd and LVIDd

z To calculate LVMW, LVMWI
1. In the M-cardiac measurement menu, roll the trackball to highlight LVM W , and press Set.
2. Measure LVPWd, IVSTd and LVIDd respectively following the prompt instruction.
3. After the measurements, the result of LVMW will be displayed in the measurement result
window. The system will display LVWMI if you have keyed in Height and Weight before the
measurement. If you had measured LV before, it will renovate the LV results.
8.2. Cardiac Measurements and Calculations in B Mode
1. Press Exam to select cardiology and press Set.
2. In B mode, press Measure, the system will enter B mode cardiac measurement. The B
mode cardiac measurement menus are shown as follows:
