Zachowanie sie ciśnienia tetniczego podczas serii pomiarów powtarzanych w krótkim odstepie czasu u normotensyjnych młodych dorosłych - Doniesienie wstepne

Introduction: According to previous studies, blood pressure (BP) tends to lower during consecutive measurements. Nevertheless it has not been reviewed whether this trend is influenced by a short break during series of measurements. Aim of study: Our aim was to analyze the results of blood pressure measurements performed in two series of consecutive readings in normotensive young adults. Material and methods: 53 young and healthy volunteers had their BP (mmHg) measured three times (I, II, III) in each of two series (S1, S2), using the oscillometric device Omron HEM-705CP. Results: Systolic BP (SBP) (mmHg) for both, S1 and S2, was lower in measurement III then in I: S1-I: 114.3 ± 16.0 vs S1-III: 111.9 ± 15.1; pII>III) was present only in 25% of participants for S1-SBP, 19% for S2-SBP, 32% for S1-DBP and 19% for S2-DBP. All the possible types of reactions were observed in the others. Conclusions: Although authors carefully tried to eliminate any factors known to cause the pressor response, lowering of BP in normotensive young adults persisted even after 15-minute-break.
