The arterial elasticity can be well reflected in arterial pulse wave velocity.Accurate measurement of arterial pulse wave velocity can be of great help to prevent and treat cardiovascular disease.A pulse wave velocity measurement system based on FPGA is designed.The system is composed of conditioning module

AD acquisition module and touchscreen control and display module.The FPGA core is configurated by SOPC Builder which synchronously acquire two path pulse signals

and then calculate the pulse wave velocity and display the waveform.Experimental results show that the system has a good interactive interface.The average pulse wave velocity of a member of the laboratory measured is 10.344m/s and the standard deviation of the pulse wave velocity is less than 0.5

the system has high stability.
