Differential sympathetic response during coronary occlusion

  • Published:
Research in Experimental Medicine

Summary

Occlusion of the circumflex branch of the left coronary artery in rabbits induces a differential response of regional sympathetic activity. The discharges of the splanchnic nerve are increased, and the discharges of a sympathetic nerve twig to the ear are inhibited. This pattern of sympathetic response is accompanied by a fall in arterial blood pressure.

Zusammenfassung

Während Okklusion des R. circumflexus der linken Coronararterie treten beim Kaninchen gegensinnige Änderungen der regionalen Sympathicusaktivität auf: Die Entladungen im N. splanchnicus nehmen zu, die Aktivität in einem Sympathicusast zum Ohr nimmt ab. Der arterielle Blutdruck fällt ebenfalls ab.
