High resistant aortic waveform
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. WebDec 2, 2024 · In contrast, high resistance vessels (e.g. external carotid artery, limb arteries) are characterized by early reversal of diastolic flow, and low or absent EDV 4. In stenosis, a localized reduction in vascular radius increases resistance, causing increased PSV and EDV distal to the stenosed site 3,4.
