Cardiology Measurements and Calculations
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
The calculation formula
LVMW (g) = 1.04*[{IVSTd (cm) +LVIDd (cm) +LVPWd (cm)}3-LVIDd3 (cm)3]-13.6
LVMWI = LVMW (g)/BSA (m)2
z
To calculate LVMW, LVMWI
1. In the M-cardiac measurement menu, roll the trackball to highlight LVMW, 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:
