一种新的手动方法来计算左心室储压力与自动化软件有很大的一致性. 这种技术为评估心脏功能提供了可靠的替代方案,尤其是在没有自动化工具的情况下.
科学领域:
- 心脏病学
- 医学成像
- 心声检查
背景情况:
- 左心房储压力是心脏功能和心血管风险的关键指标.
- 左心房应变的自动化分析并不广泛,特别是在资源有限的环境中.
研究的目的:
- 开发和验证双平面左心室储应变计算的手动方法.
- 评估手动和自动化方法在患有或没有心房的患者之间的一致性.
主要方法:
- 分析了60名患者的心声学数据 (30名心房,30名鼻节律).
- 使用自动斑点跟踪和手动点对点方法测量左心房储压力.
- 使用皮尔森相关性,布兰德-阿尔特曼分析和类内相关系数进行了评估.
主要成果:
- 在手动和自动化方法之间发现了强烈的相关性 (r=0. 95在AF中,r=0. 94在SR中) 和良好的一致性.
- 布兰德-阿尔特曼的分析显示,共识的界限很窄.
- 高的类内相关系数 (AF为0. 95,SR为0. 92) 表明了卓越的可靠性.
结论:
- 手动测量左心室储压力是可行的和可重复的.
- 这种手工方法与自动化软件非常一致.
- 在没有自动化工具的情况下,这种手动方法提供了可靠的左心房压力评估替代方案.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
