[The role of sympathetic and parasympathetic nerves in the development of vagotomic tachycardia].

According to some authors the vagus tonus isn't observed at all and the cause of vagotomic tachycardia is the sympathic nervous system excitement. Our investigations have found the causes of different opinions; in particular, we have showed that vagotomic tachycardia appears much earlier then sympathetic nervous system excitement. It confirms the earlier formulated idea about vagus tonus presence and it's role in the heart work regulation. The sympathic nervous system tonus isn't marked at all.
