在体位变化时,机体会产生一系列的适应性改变。在这一变化过程中,多数人能维持血压基本稳定(体位正常血压,orthostatic normotension,ONT),但也有部分人群出现体位性低血压(orthostatic hypotension,OH),与之相反的是体位性高血压(orthostatic hypertension,OHT)。多年来OH一直是医学界研究的热点,但OHT往往被认为是血压测量的误差或是直立后的血压正常 When the position changes, the body will produce a series of adaptive changes. In the process of change, most people maintain blood pressure basically stable (orthostatic normotension, ONT), but also some people have orthostatic hypotension (orthostatic hypotension, OH), on the contrary, orthostatic hypotension (orthostatic hypertension, OHT). OH has been a hot spot in the medical field for many years. However, OHT is often considered as an error of blood pressure measurement or normal blood pressure after erection
