Altered autonomic balance in late pregnancy warrants clinical vigilance during orthostasis; leaves open links to adverse outcomes.
Does the late stage of normal human pregnancy alter autonomic control of the circulation compared to the early stage?
Normal late pregnancy is associated with altered autonomic control of the circulation, including increased sympathetic modulation and blunted responsiveness to orthostatic stress.
Lucini et al. (1999) studied this question.
