The intermittent relaxation and contraction of the heart during each cardiac cycle cause elastic contraction of the blood vessel wall, blood pressure changes and blood flow velocity changes, the changes are propagated to tiny blood vessels along with blood in a wave mode, and the changes of the parameters are generated along with each other and can be reflected in arterial pulse waves. The waveform of the pulse wave is composed of two parts: ascending branches and descending branches. The ascending branch represents the left ventricular ejection process, the arterial blood volume is increased, the blood pressure is increased, then the blood in the aorta flows to the far end of the aorta and branches thereof, the blood volume is reduced, the blood pressure is reduced, and the descending branch of the pulse wave is formed. Different arterial segments have different blood pressures, and in peripheral micro blood vessels and capillary blood vessels, because of large peripheral resistance, reflected waves are strong, even a phenomenon of heavy pulsation waves occurs, and the reflected waves are important parts of pulse wave reflection.
