WebJul 15, 2024 · High-resistive waveforms have a sharp upstroke and brisk downstroke and may be either multiphasic or monophasic. Low-resistive waveforms contain a prolonged downstroke in late systole with continuous forward flow throughout diastole without an end-systolic notch. Low-resistive waveforms are monophasic. fish word search puzzles
