Interpretation of peripheral arterial and venous Doppler ...

The writing committee recommends that arterial spec-tral Doppler waveforms be described as demonstrating high, intermediate, or low resistance. High-resistive wave-forms have a sharp upstroke and brisk downstroke and may be either multiphasic or monophasic. Low-resistive wave-forms contain a prolonged downstroke in late systole with
