The effect of heart rate on blood pressure measurement in patients with atrial fibrillation: a cross-sectional study

This study explored the effect of heart rate (HR) on the stability and accuracy of blood pressure (BP) measurement and the optimal HR range for the most accurate blood pressure measurement in atrial fibrillation (AF) patients. A total of 583 patients (383 and 200 with AF and sinus rhythm (SR), respe...

Zusammenfassung:This study explored the effect of heart rate (HR) on the stability and accuracy of blood pressure (BP) measurement and the optimal HR range for the most accurate blood pressure measurement in atrial fibrillation (AF) patients. A total of 583 patients (383 and 200 with AF and sinus rhythm (SR), respectively) were included in this study. The noninvasive blood pressure (NIBP), invasive blood pressure (IBP), and HR were repeatedly measured ten times at 30-second intervals for every patient. Both the AF and SR groups were then subdivided into five groups depending on the HR (i.e., < 60, 60-80, 80-100, 100-120, and ≥120 bpm). The difference between the IBP and NIBP (i.e., △SBP) and the coefficient of variation (CV) were calculated, and the stability and accuracy of NIBP measurements were analyzed. CV and △SBP were significantly higher in the AF group. In the AF group, the CV of NIBP was highest when the HR was ≥ 100 bpm; and △SBP was significantly lower in the HR groups with 60-80 and 80-100 bpm (< 60 bpm, △SBP 11.62 ± 2.64 mmHg; 60-80 bpm, △SBP 7.10 ± 1.92 mmHg; 80-100 bpm, △SBP 7.10 ± 2.95 mmHg; 100-120 bpm, △SBP 10.52 ± 2.72 mmHg; ≥120 bpm, △SBP 14.15 ± 3.61 mmHg, P
