By means of some neuromorphological and physiological methods, peculiarities of the cardiac cholinergic innervation have been studied in the rabbit, guinea pig, cat, rat and man. The mammalian myocardium (the man including) is heterogeneous in its parasympathetic innervation. There are no terminal cholinergic plexuses in the external and medial layers of the myocardial ventricles, their density is not the same in other myocardial area. According to the cholinergic plexus density gradient, various parts of the atrial myocardium are distributed as following: the anterior part of the atrioventricular node and the atrioventricular fasciculus, the sinuatrial node area, the atrial septum, the right and left atria. Heterogeneity mentioned for the terminal cholinergic plexus demonstrates that various myocardial parts are not similarly subjected to the cholinergic influences.
通过一些神经形态学和生理学方法，已经对家兔、豚鼠、猫、大鼠和人类心脏胆碱能神经支配的特点进行了研究。哺乳动物的心肌（包括人类）在副交感神经支配方面是异质性的。心肌心室的外层和中层没有终末胆碱能丛，其在其他心肌区域的密度也不相同。根据胆碱能丛密度梯度，心房肌的各个部分分布如下：房室结和房室束的前部、窦房结区域、房间隔、右心房和左心房。终末胆碱能丛的这种异质性表明，心肌的各个部分受到胆碱能影响的程度不同。
