LVMWI
Left Ventricular Muscle Weight
Index
LVMWI (No unit) = LVMW/BSA
A/E
The ratio of CA to CE
A/E (No unit) = CA (mm)/CE (mm)
LAD/AOD
Left Atrium Diameter / Aortic
root Diameter
LAD/AOD (No unit) = LAD (mm) / AOD (mm)
QMV

CUBE formula
SV
Stroke volume
SV (mL) = EDV (mL)-ESV (mL)
CO
Cardiac Output
CO (L/min) = SV (mL) × HR (bpm)/1000
EF
Ejection fraction (M mode)
EF (No unit) = SV (mL)/ EDV (mL) × 100%
FS
Fractional Shortening
FS (No unit) =[ {LVIDd (mm)- LVIDs (mm)}/ LVIDd
(mm) ]x 100%
SI
Stroke Index
SI (No unit)= SV (mL)/ BSA (m

)
CI
Cardiac Index
CI (No unit)= CO (L/min)/ BSA (m

)
MVCF
Mean Velocity Circumferential
Fiber Shortening
MVCF (No unit)= { LVIDd (mm)- LVIDs (mm)}/ {LVIDd
(mm) × ET (ms)/1000}
