Vascular ageing measurements


Pulse wave velocity


Pulse wave velocity image

The most widely used measurement of arterial stiffness in both clinical and research practice. Pulse wave velocity (PWV) is measured as the time taken for arterial pressure waves to travel between two recording arteries, which are usually the carotid and femoral arteries (1). PWV provides crucial information regarding the stiffness of an artery - it becomes much faster in a stiffened artery (2).
