WebNormal human peak systolic blood flow velocities vary with age, cardiac output, and anatomic site. At the aortic valve, peak velocities of up to 500 cm/sec may be possible. The ascending aorta has the highest average peak velocities of the major vessels; typical values are 150-175 cm/sec. Web2 de dez. de 2024 · Peak systolic velocity (PSV) is an index measured in spectral Doppler ultrasound. On a Doppler waveform, the peak systolic velocity corresponds to each tall “peak” in the spectrum window 1.
