Key result
Higher daytime physical activity significantly increased measurement rejection rates during Welch Allyn Quiet-Trak ambulatory blood pressure monitoring (10±3 vs 3±2 daytime rejects; P<0.001).

Activity may confound ABPM validation; leaves open need for activity-standardized protocols.

What patient characteristics and factors confound the assessment of ambulatory blood pressure monitors during formal validation protocols?
p-value: p=<0.001
Objective measurement of physical activity and inclusion of representative patients with clinically relevant blood pressure levels are necessary to improve the reliability of ABPM validation protocols.
J.Conor O’Shea (1997) conducted an observational in Hypertension. Welch Allyn Quiet-Trak ABPM vs. Manual measurements and clinic attenders was evaluated on Measurement rejection rate (p=<0.001). Higher daytime physical activity significantly increased measurement rejection rates during Welch Allyn Quiet-Trak ambulatory blood pressure monitoring (10±3 vs 3±2 daytime rejects; P<0.001).
