ABSTRACT
PURPOSE:
Irregular heart rhythm in the course of atrial fibrillation (AFib) results in lower blood pressure (BP) measurements reproducibility which is further limited by various BP-monitors used. Therefore the aim of our study was to estimate accuracy of oscillometric BP measurement (SpaceLabs 90207) with reference to mercury manometer-based readings. MATERIAL ANDMETHODS:
Study was performed in 47 hemodynamically stable patients aged 63 ± 12 yo with paroxysmal or persistent AFib, at baseline. Patients were reassessed within one week after effective cardioversion (SR; n = 29). BP was measured using Y-tube connection allowing for simultaneous measurements on the same arm with SpaceLabs 90207 and referral method. Mean values were tested with paired t-tests. Additionally, concordance correlation coefficient (ρc) and Bland-Altman plots were assessed. Results were confronted with AAMI, and ESH-IP criteria.RESULTS:
Both during arrhythmia and sinus rhythm diastolic BP differed significantly (Δ = 4.6 ± 6.0 mm Hg, p < .001 and 2.1 ± 4.0 mm Hg, p < .001; for AFib, and SR, respectively), which was not the case for systolic BP. The ρc during arrhythmia equaled 0.89, and 0.75 for systolic and diastolic BP, respectively, which further improved while SR (0.96 and 0.89, respectively). Results confronted against AAMI and ESH-IP showed that all criteria were met except for one (60% vs. required 65% of paired differences of less than 5 mm Hg) during AFib.CONCLUSIONS:
The direct comparisons of BP readings allowed to conclude that diastolic blood pressure tended to be slightly overestimated when assessed with SpaceLabs 90207 in patients with both, AFib and SR, which was not a case for systolic BP. When the results were confronted with available validation protocols requirements, all referral criteria were met except for one. Taken together, our results suggest acceptable BP readings dispersion of SpaceLabs 90207 in BP monitoring of patients with both AFib and SR.Palavras-chave
