This method is based off of the regurgitant volume (rvol) calculation: A formula was derived for calculating mitral valve stroke volume (mvsv) using the rate of mitral valve (mv) opening (de slope on the mv echogram), the vertical disease between the mitral leaflet echoes early in diastole (ee), the electrocardiographic pr interval and. This stroke volume index calculator estimates the quantity of blood per square meter of bsa which is stroke volume divided by body surface area.
