Figure 4.

Pulmonary outflow velocity spectrum obtained from a right parasternal right ventricular inflow-outflow view. The peak velocity of the pulmonary 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 pulmonary flow were measured as shown.
