Figure 2From: Repeatability, variability and reference values of pulsed wave Doppler echocardiographic measurements in healthy Saanen goatsAortic flow velocity spectrum obtained from a left parasternal long axis five chamber view. The peak velocity of the aortic flow (Vmax), the velocity time integral (VTI), the ejection time (ET), the time to peak velocity (TTP) and the pre-ejection period (PEP) of the aortic flow were measured as shown.Back to article page
