Pregnancy Day Assessment Clinic Data

Description

The bp_preg data set includes 209 women each with 30 minute recordings during the Pregnancy Day Assessment Clinic (PDAC) observation window for up to a maximum of 240 minutes (i.e. a maximum of 8 total readings per subject per observation window in addition to an initial "booking" reading before the PDAC assessment). This recent study in obstetrics and gynecology investigated pregnancy-induced hypertension (PIH) and pre-eclampsia (PE) prediction by analyzing cardiac and physiological information to determine whether the blood pressure assessment of the first observation window of 1 hour (60 minutes) was sufficient relative to the standard 4 hour (240 minute) window.
