Popis: | This study was conducted to evaluate whether the impact factor on the accuracy of oscillometric blood pressure (BP) is different between the patients with atrial affiliation (AF) and sinus rhythm (SR). This study included 124 AF patients and 98 SR patients who underwent coronary arteriography. Upper arm oscillometric and intro-aortic BP were simultaneously measured three times, and the averages were recorded as final values, respectively. The difference between oscillometric and intro-aortic BP was recorded as delta BP. For reducing the influence of baseline BP on delta BP, a percentage difference (PD-BP) was calculated with the formula: PD-BP = delta BP/intro-aortic BP × 100%. The oscillometric SBP and DBP levels slightly underestimated intro-aortic BP (by 2.2/1.6 mmHg) in the SR group, but significantly underestimated (by 5.8/4.8 mmHg) in the AF group. Age was negatively correlated with delta SBP and positively with delta DBP in SR patients, but not correlated in AF patients. Otherwise, ventricular rate (VR) was negatively correlated with delta SBP or delta DBP in AF, which indicated that the accuracy of oscillometric BP declined as the VR increased. With intro-aortic BP as reference, the accuracy of oscillometric BP in AF patients is lower than SR patients. Meanwhile, age may impact the oscillometric BP accuracy in SR patients, but VR may impact that in AF patients. |
