Studies of the origin and route of the SANB in human hearts have produced discrepant findings and therefore in this study we macroscopically investigated the origin, route, and distribution of the SANB in 100 human hearts. In addition, we examined the relationship between the coronary artery dominance and numbers of the branches, origin of the SANB. The SANB was found to take one branch in 91cases (91.0%), two branches in 8 cases (8.0%), and three branches in one case (1.0%). Right coronary artery dominance was found in 57 cases (57.0%), while balanced coronary circulation and left coronary artery dominance was found in 28 cases (28.0%) and 15 cases (15.0%). The origin of the SANB was independent of coronary arterial dominance.}, pages = {49--52}, title = {A Study of the Arteries distributed in the Sinuatrial Node of Human Heart : relationship between the Coronary Arterial Dominance and the Origin of the Sinuatrial Nodal Branch}, volume = {24}, year = {2014} }
