Beat-to-beat variability of blood pressure (BP) hampers its exact measurements in patients with arrhythmias, which can give rise to diagnostic inaccuracies and accordingly wrong treatment. Aim: to assess whether BP measurement might be exact in patients with permanent atrial fibrillation when using the latest generation of high-accuracy oscillometric devices. Subjects and methods. The developed design was used to examine 15 patients and to make 44 comparisons of BP measurements. The inclusion criteria were permanent atrial fibrillation and evidence for hypertension. Results. BP levels measured by an objective auscultatory method (OAM), a traditional auscultatory method (TAM), and OMRON M6 device were compared. Considerable (more than 10 mm Hg) differences were found in the recordings taken by OAM and OMRON M6 during 6 (14%) systolic BP (SBP) and 4 (9%) diastolic BP (DBP) measurements. However, substantial differences were concurrently revealed in those obtained by the two auscultatory methods TAM and OAM in 3 (7%) and 4 (9%) measurements of SBP and DPB, respectively; which appears to be related to the general problems of BP measurements in arrhythmias. Conclusion. The conducted pilot study has generally confirmed that the up-to-date high-grade oscillometric tonometers (such as an OMRON 6) may be used to measure SBP and DBP levels in the presence of atrial fibrillation.
