文摘
Arterial pulse waveform is a complex integration of multiple wave components travelling the arterial system during cardiac cycle. As pulse wave advances throughout the arterial system it is reflected at sites where impedance of the vasculature abruptly vary. Based on pulse waveform analysis a simple method is proposed to estimate both the precise location of lower limb natural arterial reflection site and pulse wave velocity.
