Svr stroke volume ratio
Did you know?
The stroke volume (SV), cardiac output (CO), and systemic vascular resistance (SVR) are all derived from two ultrasound measurements: the left ventricular outflow tract diameter (LVOTD) and the left ventricular outflow tract velocity time integral (LVOT VTI) . Visualizza altro WebThe equations LVEF = 86.168 - 0.011 × SVR and VTI = 41.23 × e (-0.0005×SVR) were found to provide "predicted" values for given SVR.
