Different reflex responses in cardiac and renal sympathetic nerve activities during coronary occlusion in the dog.

Suehiro et al. (1982) studied Experimental myocardial ischemia (n=22). Left circumflex coronary artery occlusion vs. Pre-occlusion baseline was evaluated on Per cent changes in cardiac sympathetic nerve activity (CSNA) and renal nerve activity (RNA). During a 1-minute coronary occlusion in dogs, renal sympathetic nerve activity was inhibited significantly more than cardiac sympathetic nerve activity by reflexes mediated through afferent vagal nerves.
