电力生理学电力生理学
心脏节律失常映射心脏节律失常映射

背景情况:

像OCTARAY和OPTRELL这样的多电极映射导管对于心律失常的电解剖学映射至关重要.
有限的研究比较了这些先进的映射导管的性能.

研究的目的:

为了比较OCTARAY和OPTRELL导管在左心房 (LA) 地图绘制中在心房动 (AF) 废除期间的性能.
为了评估它们在早发性心室收缩 (PVC) 映射中的有效性.

主要方法:

20名患者接受了LA或PVC测绘.
在OCTARAY和OPTRELL之间比较了映射参数,包括时间,点,导管诱导事件,组织近距离指示 (TPI),电压和光镜时间.

主要成果:

与OCTARAY相比,OPTRELL在LA映射中显示出明显更高的平均电压 (p=0.001) 和TPI阳性电极 (p<0.001) 在LA映射中.
在PVC测绘中,OPTRELL产生的PVC导管诱导的PVC (p=0.039) 比OCTARAY少得多.

结论:

在LA电压和TPI评估中,OPTRELL提供了更好的性能.
与OCTARAY相比,OPTRELL在PVC测绘过程中显示了导管诱导PVC的减少.

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
