But it is very difficult to observe the blood flow in the subendocardial. Fortunately the high speed CCD microscope provides a powerful tool.
但是，观测心内膜血流是十分困难的，而高速CCD显微镜为观测提供了有力的工具。

The myocardium beneath the endocardial surface at the top demonstrates pale fibrosis with collagenization following healing of a subendocardial myocardial infarction.
图上方心内膜下的心肌可见苍白色纤维化，是心内膜下心肌梗死治疗后形成的。
