METHODS: Data from 53 737 subjects from the National Health and Nutrition Examination Survey were analyzed. In each subject, three consecutive BP measurements were performed with a minimum time-interval of at least 30 s. We propose three patterns of within-visit BP variability (separately for SBP, DBP and PP): (1) increasing trend (BP3 &gt; BP2 &gt; BP1); (2) decreasing trend (BP1 &gt; BP2 &gt; BP3) and (3) no trend (BP3 ≈ BP2 ≈ BP1). A threshold of minimum change (ΔP &gt; 3 mmHg) between BP1-BP2 and BP2-BP3 was also applied as a prerequisite for the definition of these trends.

RESULTS: An increasing trend was observed among three consecutive measurements of SBP, DBP and PP in 7.4, 10.4 and 10.2%, respectively. When a minimum threshold of 3 mmHg was set the respective increasing trends were observed in 1.8, 2.9 and 4.4%, respectively. There was a higher prevalence of decreasing trend within three consecutive SBP, DBP and PP readings: 17, 13.1 and 16.2%, respectively, whereas using a threshold of ΔP &gt;3 mmHg the respective prevalence was 6.3, 4.1 and 7.7%. A maximum absolute difference &gt;10 mmHg within triplicate of SBP/DBP/PP readings was observed in 12.9, 13 and 29.4%, respectively. In the era of personalized medicine, these patterns are well worth further investigation concerning their pathophysiologic and clinical relevance.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/32106147?dopt=Abstract</style></custom1></record></records></xml>
