概括
在心房动 (AF) 期间,对大动脉硬度的评估是可行的. 一个位点的方法提供了可靠的脉冲波速度 (PWV) 和中心血压 (BP) 的测量,其变化比两位点的方法要小.
科学领域:
- 心血管生理学心血管生理学
- 生物医学工程 生物医学工程
- 临床诊断 临床诊断 临床诊断
背景情况:
- 评估大动脉硬度对于心血管风险分层至关重要.
- 目前用于测量大动脉硬性的方法在心房动 (AF) 患者中缺乏验证.
- 需要对AF中大动脉硬性的可靠评估,以指导治疗和预测结果.
研究的目的:
- 评估不同方法的可靠性,以评估在患有持续性AF的患者中大动脉硬性的可靠性.
- 为了比较脉冲波速度 (PWV),中心血压 (BP) 和增高指数 (AIx) 在AF期间和心转动后与鼻节律 (SR) 的测量.
主要方法:
- 用两位点的平面化方法和一个位点的袖口式振荡计方法测量了带到关节和大动脉脉冲波速 (cf/aoPWV),中心BP和AIx.
- 在40名患有持续性AF的患者中进行了测量,并在心脏转向SR后重复测量.
- 分析的重点是比较两种方法之间的测量变化和一致性,以及AF和SR状态之间的测量.
主要成果:
- 两站式方法显示,与SR相比,AF期间PWV的变异性更高 (SD2.5对1.0m/s).
- 一个地点的方法显示了类似的PWV值和AF和SR之间的较低变化 (SD 0.7与0.6 m/s).
- 这两种方法都表明AF期间的中心BP更高,AIx更低,而单位方法需要更少的重复测量.
结论:
- 通过使用适当的方法,可以在AF期间可靠地评估大动脉硬.
- 基于袖口的单站式振荡计方法是可取的,因为与双站式平面化方法相比,波动性较低,所需的测量较少.
- 研究结果表明,AF期间中央BP和AIx发生显著变化,影响大动脉硬度评估.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Assessment of blood pressure in brachial artery(two-step method)
660
Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
