Measuring blood pressure in the elderly: does atrial fibrillation increase observer variability?
OBJECTIVE To compare the interobserver and intraobserver variability of blood pressure measurements in geriatric patients in atrial fibrillation and in sinus rhythm. DESIGN Prospective assessment of blood pressure measurements carried out in random order in two groups of elderly patients by five doctors unaware of the aims of the study. SETTING Acute assessment wards for geriatric medicine,...
متن کاملAuscultatory versus oscillometric blood pressure measurement in patients with atrial fibrillation and arterial hypertension
BACKGROUND The aim of our study was to investigate the reliability of automated oscillometric blood pressure (BP) monitoring in the presence and absence of atrial fibrillation (AF) in hypertensive patients. METHODS BP was measured and compared in 71 randomly selected patients with AF and arterial hypertension diagnosis, 4 times each by auscultatory and oscillometric (Microlife BP A6 PC with A...
متن کاملRespiratory systolic pressure variability during atrial fibrillation and sinus rhythm.
Previous studies have found that respiratory variations of ventricular response in atrial fibrillation are infrequent and inconsistent. This asynchrony between heart rate and respiration may characterize the physiological mechanisms coupling heart rate and systolic blood pressure oscillations in the respiratory band. The aim of this study was to evaluate whether synchronous variations in systol...
متن کاملNighttime ambulatory blood pressure is associated with atrial remodelling and neurohormonal activation in patients with idiopathic atrial fibrillation.
INTRODUCTION AND OBJECTIVES Hypertension is a risk factor for atrial fibrillation. Activation of the renin-angiotensin-system seems to be involved in atrial enlargement, with release of atrial and brain natriuretic peptides. The aim of this study was to evaluate the relationship between ambulatory blood pressure and levels of natriuretic peptides, with left atrial size in normotensives with idi...
متن کاملPatients With Atrial Fibrillation
Background: The method described provides a rational means for determining whether to institute chronic anticoagulation to prevent stroke in patients with chronic atrial fibrillation under a variety of clinical circumstances. Summary of Comment: The concept of expected value is used in conjunction with data from clinical studies to define the net value of anticoagulation to the patient. A full ...
