Hemodynamic Correlates of Late Systolic Flow Velocity Augmentation in the Carotid Artery

Figure 1

(a) Simultaneous measurement of CCA diameter changes (pink lines) creating the distension waveforms (analogous to a pressure waveform) and CCA blood flow velocity waveforms (dark blue) from echo tracking and color Doppler. (b) Representative view of results obtained from WIA. From top to bottom: distension (pressure) waveform, flow velocity waveform, wave intensity analysis ( , , and NA), and ECG.
