Abstract

It was studied the arterial blood supply of the sinus node in 20 Minke whales - 12 males and 8 females; the hearts were dissecated after fixation in formalin. It was observed that 15 times (75.0% ± 9.7) the nourishment of the node depends only of the ramus proximalis atrii dextri and 5 times (25.0% ± 9.7) it depends exclusively of the ramus proximalis atrii sinistri. They were registered 2 cases of arterial anastomosis between the implied vessels in the blood supply of the sinus node.
