Two pacemakers localized in sinoatrial and atrioventricular valves were revealed in the tench heart. In their absence, the ventricular and sometimes the atrial myocardium are capable of initialting the automaticity. Pacemaker's cells of the sinoatrial valve are surrounded by specific area similar to sinoauricular ring in amphibia or sino-caval region in mammals. Characteristics of the action potential in different parts of the tench heart are presented.
在丁鱥心脏中发现了位于窦房瓣和房室瓣的两个起搏器。在没有这些起搏器的情况下,心室肌有时还有心房肌能够引发自律性。窦房瓣的起搏细胞被类似于两栖动物的窦耳环或哺乳动物的窦腔区域的特定区域所包围。文中呈现了丁鱥心脏不同部位动作电位的特征。
