Parvus tardus waveform carotid

WebIV Pulsus Parvus ET TardusA The Finding and Technique. Pulsus parvus et tardus describes a carotid pulse with a small volume (pulsus parvus) that rises slowly and has a delayed systolic peak (pulsus tardus; see Fig. 15.1). 22 It is routinely detected by palpation. B Clinical Significance. Pulsus parvus et tardus is a finding of aortic stenosis. Web27 Dec 2016 · Decreased diastolic flow in this common carotid artery is seen proximal to (upstream from) the point of maximal stenosis. This is a result of increased resistance in the vessel caused by the downstream stenosis present in the internal carotid artery. ...
