[Sympathetic and parasympathetic regulation of the heart in transitory coronary insufficiency].
Experiments were made on 480 rats and 60 rabbits with transitory insufficiency (duration of myocardial ischemia 10.40 and 120 min the length of subsequent reperfusion 40-60 min). It was discovered that there was natural development of the phenomenon of limitation of drawing the heart in direct and reflectory reactions of the circulation system within the increase of duration of local ischemia and the beginning of the subsequent reperfusion. The phenomenon of "limitation", which is realized with the involvement of sympathetic and parasympathetic mechanisms, promotes a decrease of the extent of heart alteration during its local ischemia and increase of reparative process in the heart at the reperfusion period.
