The cervical cardiac branches (sometimes ambiguously called superior cardiac branches) of vagus nerve, two or three in number, arise from the vagus, at the upper and lower parts of the neck. The upper branches are small, and communicate with the cardiac branches of the sympathetic. They can be traced to the deep part of the cardiac plexus.
Upon leaving the medulla oblongata between the olive and the inferior cerebellar peduncle, the vagus nerve extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down to the neck, chest, and abdomen, where it contributes to the innervation of the viscera, reaching all the way to the colon.
The only cardiac nerves which do not enter into the formation of the deep part of the cardiac plexus are the superior cardiac nerve of the left sympathetic trunk, and the lower of the two superior cervical cardiac branches from the left vagus nerve, which pass to the superficial part of the plexus.
Each recurrent laryngeal nerve supplies the larynx, the heart, the trachea and the esophagus. Another set of nerves that come off the vagus nerves approximately at the level of entering the thorax are the cardiac branches of the vagus nerve. These cardiac branches go on to form cardiac and pulmonary plexuses around the heart and lungs. As the ...

A dad, 45, had what seemed like a pinched nerve. It was a sign of a cancerous thymoma. Chest pain, shortness of breath were signs of his thymoma.
the vagus nerve, part of the parasympathetic branch of the autonomic nervous system, to lower heart rate. The cardiovascular centre also increases the stroke volume of the heart (that is, the amount of blood it pumps). These two changes help to regulate the cardiac output, so that a sufficient amount of blood reaches tissues.
