体位性低血压研究主要集中于立位低血压,对于坐位低血压的研究较少。实际上,血压的体位变化应涉及卧位-坐位和坐位-立位之间的血压差异。虽然在临床工作中坐位低血压并不少见,但没有得到足够的关注。1坐位血压与卧位血压通常认为卧位血压与坐位血压相似~([1])。但目前有关卧位血压与坐位血压差异的研究不多,尤其缺乏大规模的流行病学调查,一些小型研究报道的结果也不 Research on orthostatic hypotension mainly focuses on standing hypotension, and there is little research on sitting hypotension. In fact, changes in the position of the blood pressure should involve differences in blood pressure between the lying position and the sitting position. Although sitting in the blood pressure is not uncommon in the clinical work, but did not get enough attention. 1 sitting blood pressure and supine blood pressure is generally considered supine blood pressure and sitting blood pressure is similar to ~ ([1]). However, little is known about the differences in blood pressure between the supine position and the sitting position. In particular, large-scale epidemiological investigations are lacking and the results reported by some small studies are not
