Establishes normative ABPM curves for pregnancy; leaves open predictive value for outcomes in prospective cohorts.
What are the normal ambulatory blood pressure and heart rate values during different periods of pregnancy compared to nonpregnant women?
Ambulatory blood pressure monitoring establishes normal physiological curves during pregnancy, demonstrating a mid-pregnancy dip in blood pressure and a continuous elevation in heart rate.
Ferguson et al. (1994) studied this question.
