成熟个体中，心外膜来源的祖细胞分化形成心脏，但是一旦分化之后，这些祖细胞就进入休眠状态。
结果表明在心外膜按一定路线射频消融治疗AF是可行的。
本文提出了一种MR心脏图像的左心室内外壁的联合分割和时序追踪的新方法。
1·One water sac was placed on the epicardium and the exploration was performed by the detecting head on the water sac.
然后将其行开胸手术，悬吊心包，在心外膜上放置一水囊，将探头放置于水囊上进行探查。
2·The transverse fibers began to appear in the middle and inferior segments of CT near epicardium.
从界嵴的中部向下，近心外膜侧，开始出现横行纤维。
3·These ganglia mainly lie under the epicardium and in coronary sulcus.
这些神经节主要分布在心外膜下，以及冠状沟内。
4·Objective To investigate the relationship between epicardium adipose thickness and the severity of coronary artery stenosis in patients with coronary artery disease.
目的探讨冠心病患者心外膜脂肪厚度与冠状动脉狭窄程度的关系。
5·Seen over the surface of the epicardium are pale white-tan nodules of metastatic tumor.
在心外膜的表面可见灰白色转移性肿瘤结节。
