Ultrastructure of the cells generating the action potential, specific for the pacemaker of the sinuous-auricular node has been studied. The cells are labelled with lanthanum chloride by means of the registrating microelectrode. Two types of pacemakers are revealed. The cells of one type contain specific auricular granules, while those of the other type do not contain them. The pacemaker-cells of the sinuous-auricular node have some peculiarities in the structure of the contractile apparatus, mitochondria, Golgi complex, intercellular contacts owing to which their morphological identification is possible.
对产生动作电位的细胞超微结构进行了研究，这些细胞是窦房结起搏器所特有的。通过记录微电极用氯化镧对这些细胞进行标记。发现了两种类型的起搏器。一种类型的细胞含有特定的心房颗粒，而另一种类型的细胞则不含这些颗粒。窦房结的起搏细胞在收缩装置、线粒体、高尔基体、细胞间连接的结构上有一些特点，据此可以进行形态学鉴定。
