Pregnancy-related BRS reductions should not yet change practice; extends physiologic understanding but remains hypothesis-generating for hypertensive disorders.
Does normotensive pregnancy alter baroreceptor sensitivity for heart rate compared to the non-pregnant state?

Blake et al. (2000) studied this question.
