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 < 0.05). The stability and accuracy of the NIBP in the SR groups were not affected by the HR. In AF patients, the NIBP stability was low when the HR was high, and the NIBP was often underestimated when the HR was high or low. Sixty to 100 bpm is the best HR range for measuring blood pressure in AF patients.
这项研究旨在探讨心率（HR）对血压（BP）测量稳定性和准确性的影响，以及在心房颤动（AF）患者中测量血压最准确的最佳 HR 范围。共有 583 名患者（383 名和 200 名分别患有 AF 和窦性节律（SR））纳入本研究。对每位患者每隔 30 秒重复测量 10 次非侵入性血压（NIBP）、侵入性血压（IBP）和 HR。然后，根据 HR（即 <60、60-80、80-100、100-120 和 ≥120bpm）将 AF 和 SR 两组进一步分为五组。计算 IBP 和 NIBP 之间的差值（即△SBP）和变异系数（CV），并分析 NIBP 测量的稳定性和准确性。AF 组的 CV 和△SBP 明显更高。在 AF 组中，当 HR ≥100bpm 时，NIBP 的 CV 最高；而在 HR 为 60-80 和 80-100bpm 时，△SBP 显著降低（<60bpm，△SBP 为 11.62±2.64mmHg；60-80bpm，△SBP 为 7.10±1.92mmHg；80-100bpm，△SBP 为 7.10±2.95mmHg；100-120bpm，△SBP 为 10.52±2.72mmHg；≥120bpm，△SBP 为 14.15±3.61mmHg，P<0.05）。SR 组的 NIBP 稳定性和准确性不受 HR 影响。在 AF 患者中，HR 较高时 NIBP 稳定性较低，而 HR 较高或较低时 NIBP 常被低估。60-100bpm 是测量 AF 患者血压的最佳 HR 范围。
