Morphofunctional organization of sinoatrial node in rat heart.
The distribution of pacemaker cells along the sinus node artery was studied under conditions of short-term culturing using intracellular glass microelectrodes. The functional borders of the central and peripheral parts of the sinoatrial node were determined. The relationship between the position of the central part of the sinoatrial node and the patterns of the sinus node artery branching were analyzed.
