在1974年以后有人注意到人的慢纤维和心肌纤维在某些生化结构方面有相似之处。骨骼肌和心肌的亚细胞结构,包括细胞器如线粒体,肌浆网和横管等亦相似。在长期的电刺激下,快和慢的肌凝蛋白能共存于单个肌纤维内。因而,一些研究者尝试将骨骼肌移植到右心室肌上或内。本研究旨在观察 It is noticed after 1974 that human slow and cardiac fibers have similar biochemical structures. Subcellular structures of skeletal and cardiac muscle, including organelles such as mitochondria, sarcoplasmic reticulum and transverse tubes, are also similar. Under long-term electrical stimulation, fast and slow myosins can coexist in a single muscle fiber. Thus, some researchers have attempted to transplant skeletal muscle onto or within the right ventricular muscle. This study aims to observe
