The pulse wave (PW) is a complex physiological phenomenon observed and detected in blood circulation. In the cardiac systole, a specified volume of blood is ejected and it moves in arteries due to transformation of the potential and kinetic energy of the ejected blood. In an artery or in a vein where the pulse wave is propagating, three dependable phenomena can be observed: blood streaming (streaming pulse), the increase of blood pressure (pressure pulse) and distension of the transverse profile (profile or volume pulse). The invasive method as well as several non-invasive methods is available to detect the PW. The PW shape varies in different parts of circulation. It depends on physiological or pathophysiological conditions of the organism. To the physiological factors the heart rate, the body height and the age belong. The pathological conditions like arteriosclerosis or diabetes can change the arterial elasticity. Hypertension or some heart diseases influence the PW velocity.
脉搏波（PW）是在血液循环中观察和检测到的一种复杂生理现象。在心脏收缩期，一定体积的血液被射出，由于射出血液的势能和动能转化，血液在动脉中流动。在脉搏波传播的动脉或静脉中，可以观察到三种相关现象：血流（血流脉搏）、血压升高（压力脉搏）和横向轮廓扩张（轮廓或容积脉搏）。检测脉搏波有侵入性方法以及几种非侵入性方法。脉搏波的形状在循环的不同部位有所不同。它取决于机体的生理或病理生理状况。生理因素包括心率、身高和年龄。诸如动脉硬化或糖尿病等病理状况会改变动脉弹性。高血压或某些心脏病会影响脉搏波速度。
