| Abstract: | The distribution of pacemaker cells and atrial working cardiomyocytes in the anterior right atrial wall was studied using intracellular glass microelectrodes under conditions of shortterm culturing. It was shown that the dominant pacemaker region and the functional tail are located in the lateral area of the central part of the sinoatrial node, while the medial area is occupied by latent pacemaker cells. |
