这项研究比较了不同软件的左心房应变 (LAS) 测量结果,发现了显著的差异. 软件的选择会影响LAS值,这凸显了临床实践中需要谨慎解释的必要性.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 左心房应变 (LAS) 参数,包括储 (LASr),导管 (LAScd) 和收缩 (LASct),越来越多地用于心力衰竭和膜病变.
- 商业上可用的菌株软件被销售为独立于供应商,但缺乏外部验证和定义的正常范围.
研究的目的:
- 使用当代菌株软件评估和比较LAS值,参考范围和相关因素.
- 评估不同LAS量化工具的供应商中立性和性能.
主要方法:
- 100名健康受试者接受了跨胸腔心声扫描.
- 使用TomTec,EchoPAC,速度向量成像 (VVI) 和Epsilon软件来量化LAS.
- 统计分析确定了与LASr变异性相关的因素,包括年龄和软件类型.
主要成果:
- 在软件包之间观察到LASr平均值的显著差异:EchoPAC和Epsilon的平均值低于TomTec和VVI.
- 年龄和特定的软件 (EchoPAC,Epsilon vs. TomTec) 与 LASr 测量变化有显著的关联.
- 还确定了参考范围和影响LAScd和LASct的因素.
结论:
- 与TomTec和VVI相比,EchoPAC和Epsilon软件报告了较低的LAS平均值.
- 虽然EchoPAC被销售为供应商中立,但显示出供应商依赖性 (仅GE扫描).
- 这些发现强调了在LAS分析中考虑软件特定的正常范围和潜在的供应商影响的重要性.

Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...
Special considerations while measuring blood pressure
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.

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...
