TYPES OF ORTHOSTATIC REACTIONS OF ARTERIAL PRESSURE AND THEIR CLINICAL SIGNIFICANCE

Orthostatic reactions of arterial pressure (AP), their patophysiological mechanisms, methods of definition and types are reviewed in this article. Attention is paid to clinical manifestations of orthostatic reactions of AP and their association with various diseases. It is noted that not all types of orthostatic reactions of AP are well investigated, for example hyper- and normotensive reactions. The largest number of works are devoted to hypotensive reactions of AP. However, it seems to be important to study prognostic significance of hyper-and normotensive reactions of AP.
