Comparative StudyA comparison of two ambulatory blood pressure monitors worn at the same time.
There are limited data in the literature comparing two simultaneously worn ambulatory blood pressure (BP) monitoring (ABPM) devices. The authors compared BPs from two monitors (Mobil-O-Graph [I. E. ⋯ The Spacelabs monitor recorded a 10.2-mm Hg higher systolic pressure in the nonrandomized (P=.0016) and a 7.9-mm Hg higher systolic pressure in the randomized studies (P=.00008) compared with the Mobil-O-Graph. The mean arterial pressures were 1 mm Hg to 2 mm Hg different between monitors in the two studies, and heart rates were nearly identical. Our observations, if confirmed in larger cohorts, support the concern that ABPM device manufacturers consider developing normative databases for their devices.
