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)

)/1000
CUBE formula
ESV End Systolic Volume
ESV (mL) = LVIDs
3
(mm

)/1000
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}
