Web1 Feb 2024 · Post-LVAD Doppler imaging demonstrated parvus tardus waveform. Analysis of flow velocities revealed that peak systolic velocity was diminished after LVAD placement in both the internal and common carotid arteries (P = 0.006 and P < 0.0001, respectively). End-diastolic velocity, however, increased post-LVAD ( P < 0.0001). 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.
