Echo Calculator The information and calculators provided here are solely for educational and descriptive purposes. These calculators should not be used in the clinical setting for patient management. BSA BSA The Du Bois formula is used here to determine BSA. Formula: BSA=0.007184 x height (cm) to the power of 0.725 x weight (kg) to the power of 0.425. Weight (kg) * Height (cm) * Body Surface Area (m2) If you are human, leave this field blank. Calculate Δ Fractional Shortening Fractional Shortening Fractional Shortening (%) can be used to quantify LV systolic function. The measurements for LV dimensions in diastole and systole are made in the PLAX view. 2D or M-mode can be used, although 2D is preferred.

Summary Δ Hemodynamics Hemodynamics Determine Stroke Volume, Cardiac Output and indexed values. The left ventricular outflow tract (LVOT) diameter and velocity time integral (VTI) need to be measured. This can be done in the apical 3 chamber or apical 5 chamber view, where the LVOT and AV are in good alignment for doppler interrogation. Weight (kg) * Height (cm) Body Surface Area (m2) Heart Rate (/min) * LVOT VTI (cm) * LVOT Diameter (cm) * LVOT CSA (cm2) Stroke Volume (ml) Cardiac Output (l/min) Stroke Volume Index (ml/min/m2) Cardiac Index (l/min/m2) If you are human, leave this field blank. Summary Start Over Δ EPSS EPSS E-point septal separation can be used to determine LV systolic function. EPSS refers to the distance between the tip of the mitral valve anterior leaflet and septal LV wall in end diastole. It is measure with M-Mode. A value greater than 10 mm is indicative of severe LV systolic failure. EPSS less than 7 mm is consistent with normal systolic function.

Submit Δ RV FAC RV FAC Right Ventricular Function can be evaluated by fractional area change (FAC%). A value of > 35% correlated with normal RV function. The measurement is made in the apical 4 chamber view. This method is dependent on accurate measurements of RV area and has its limitations.

Summary Start Over Δ RV Dimensions RV Dimensions RV Dimensions can be measured in the apical 4 chamber view. The basal, mid-cavity and longitudinal dimensions are measured. RV wall thickness is measured in the SC4C view.
