Abstract:
Objective:To study the relationship between different pulse forces and cyclical power(CP)of radial artery motion.Methods:39 patients’and 20 healthy persons’ ECG and pressure sphygmograms were collected synchronously with NX-1 sphygmograph.On the basis of automatic detecting R waves of ECG and FFT analysis of pressure sphygmograms with SPTool of MATLAB 7.0.1,change in frequency domain of radial artery motion with different forces was observed and CP was worked out.Results: There is signifi cant deviation between CP of pulse tracings with different forces(pulse tracings with powerful force〉pulse tracings with normal force〉pulse tracings with weak force).Conclusion: CP of radial artery motion can be used to discriminate pulse force.
