Supports prioritizing 48-hour duration over sampling frequency for ABPM reproducibility in pregnancy; leaves open effects on diagnostic accuracy.
Does the duration and frequency of ambulatory blood pressure sampling affect the reproducibility and diagnostic accuracy of hypertension in pregnancy?
In pregnant women, the reproducibility of ambulatory mean blood pressure values depends more on the duration of monitoring (48 hours) than on the frequency of sampling.
Hermida et al. (2003) studied this question.
