The sinuatrial nodal artery in the human heart.
Studies were performed on 12th hearts taken from cadavers of adults of both sexes. The corrosive technique was used. Arteries were filled with vinyl polychloride or Plastogen G from the side of aortic sinuses. The sino-atrial nodal artery arose as the anterior, intermediate and posterior atrial branches both from the right coronary artery and the left coronary artery. In 51.7% of the hearts the sino-atrial nodal artery formed the arterial circle at the base of the superior vena cava.
