Abstract:
Postural orthostatic tachycardia syndrome (POTS)is a clinical syndrome and the main clinical manifestation is the increase of heart rate.POTS is significantly related to position change.During the first 10 min of position change from supine to standing,if heart rate increases over a certain extent,POTS can be diagnosised.The pathogenesis of POTS has not been completely clear.The current studies show that it is closely related to the changes of central blood volume,dysautonomia,muscle pump dysfunction,vascular endothelium function disorder,etc.
