Pulse Wave Velocity (PWV)
- Aortic PWV is a direct measurement of aortic stiffness and is considered to be the gold standard of arterial stiffness measurements
- PWV is a measure of the speed of the arterial pressure waves travelling along the aortic and aorto-iliac pathway.
- Higher arterial pressure wave velocity is indicative of stiffer arteries.
- In general, measurements are performed by recording pressure waveforms at the carotid artery followed by the femoral artery, with an ECG signal being recorded simultaneously.
- PWV is calculated using the mean time difference and the arterial path length between the two recording sites.
