概括

心声回声学测量的可复制性,包括全球纵向应变 (GLS) 和顶峰心房纵向应变 (PALS),在实验室中进行了评估. 即使在心房动患者中,GLS和PALS也表现出优异的可重复性,这支持了它们更广泛的临床应用.

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:

声心图对于评估心脏功能至关重要.
心声回声学测量的中心间变异性可能会影响临床试验和注册数据.
在之前的研究中,标准心声回声学参数已经显示出低于最佳的可重现性.

研究的目的:

评估关键心声图测量的中心间可重复性.
为了比较标准回声多普勒参数的可重现性,使用先进的技术,如全球纵向应变 (GLS) 和顶峰心房纵向应变 (PALS).
在患有鼻节律 (SR) 和持续性心房动 (AF) 的患者中评估可再生性.

主要方法:

16个心声回声实验室参与了EACVI-Afib Echo Europe研究.
标准回声多普勒参数,GLS和PALS在10名SR和10名AF患者的存储回声检查上进行了测量.
为了评估测量可重复性,计算了类间相关系数 (ICC).

主要成果:

标准参数,如左心室质量和射出分数,显示出低于最佳的ICC.
减速时间表现出较差的可重现性,特别是在AF患者中 (ICC=.50).
GLS显示出高可重现性 (SR中的ICC=.81,AF中的ICC=.78). PALS显示出适当的可重现性,基于心声回声图的变化.

结论:

在注册表中应谨慎使用标准回声心脏学变量,因为其可再生性不够理想.
GLS和PALS提供优越的复制性,即使在心房的患者中也是如此.
建议在临床实践和研究中更广泛地采用GLS和PALS.

Imaging Studies for Cardiovascular System I:Echocardiography

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Correlation between ECG and Cardiac Cycle

Correlation between ECG and Cardiac Cycle

The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
