• Cardiology
  • LVOT VTI

• Cardiac output = SV x HR
• SV = CSA (cross sectional area) of LVOT x LVOT VTI
• CSA of LVOT = πr2 = π(d/2)2

Therefore CO = (LVOTd/2)2 x π x LVOT VTI x HR

$CO=(\frac{LVOTd}{2})^2\times\pi\times LVOT\space VTI\times HR$

The diameter of the LVOT was 1.94 cm, and the VTI was 6.58 cm. The calculation is (1.94 cm/2)2 × π × 6.58 cm = 19.44 cm3
