Oh, J.K., J.B. Seward, A.J. Tajik. The Echo Manual. 2nd ed., Boston: Little, Brown and Company, (1994),
p.44.
SV = (LVEDV – LVESV)
where:
SV = Stroke Volume
LVEDV = End Diastolic Volume
LVEDSV = End Systolic Volume

Tricuspid Valve Area (TVA)
Oh, J.K., J.B. Seward, A.J. Tajik. The Echo Manual. 3rd ed., Philadelphia: Lippincott, Williams, and Wilkins,
(2007), p.73-74.
TVA = 220 / PHT
Velocity Time Integral (VTI) in cm
Reynolds, Terry. The Echocardiographer's Pocket Reference. 2nd ed., School of Cardiac Ultrasound,
Arizona Heart Institute, (2000), p.383.
VTI = sum of abs (velocities [n])
where:
Auto Trace – distance (cm) blood travels with each ejection period. Velocities are absolute values.

Pregnancy." The Journal of Reproductive Medicine,35:7 (July 1990), p.674-677.
Average Ultrasound Age (AUA)
The system provides an AUA derived from the component measurements from the measurement tables.
Estimated Date of Delivery (EDD) by Average Ultrasound Age (AUA)
Results are displayed as month/day/year.
EDD = system date + (280 days – AUA in days)
