体位性低血压的两种分型

体位性低血压是老年人中常见的体征，也是心脑血管疾病和跌倒的独立危险因素，并增加全因死亡率。目前在研究体位性低血压时，越来越多采用连续无创血压测量设备，且常结合直立倾斜试验，并根据血流动力学参数进行分型。本综述将重点介绍公认的两种分型，即形态学分型及生理学分型。

Two classification systems for orthostatic hypotension

As a common physical sign in the elderly, orthostatic hypotension is an independent risk factor of cardi cerebro vascular diseases and falls, and also increases all-cause mortality. Nowadays, continuous noninvasive blood pressure measurement systems are increasingly used in the study of orthostatic hypotension, and usually combined with head-up tilting. Furthermore, orthostatic hypotension is classified by hemodynamic parameters. This review focused on two acknowledged classification systems, morphological classification and physiological classification.
