The reliability of the baroreflex sensitivity measurement has not yet been established. Thus, the objective of this study was to define intra-rater reliability of baroreflex sensitivity (BRS) measurements of the Valsalva maneuver (VM) in healthy individuals. Twenty-two healthy volunteers underwent VM testing at two time points. Intra-rater reliability was determined by the intra-class correlation coefficient (ICC), standard error of measurement and minimal detectable difference. Vagal BRS showed good reliability (ICC=0.84), while alternative adrenergic BRS was moderately reproducible (ICC=0.61). Vagal and alternative adrenergic components of BRS in VM are reliable measurements.
压力反射敏感性测量的可靠性尚未确立。因此，本研究的目的是确定健康个体中瓦尔萨尔瓦动作（VM）的压力反射敏感性（BRS）测量的评分者内信度。22名健康志愿者在两个时间点接受了VM测试。评分者内信度由组内相关系数（ICC）、测量标准误差和最小可检测差异确定。迷走神经BRS显示出良好的信度（ICC=0.84），而替代性肾上腺素能BRS的可重复性中等（ICC=0.61）。VM中BRS的迷走神经和替代性肾上腺素能成分是可靠的测量指标。
