[Seasonal changes in blood pressure and certain indicators of cardiac contractile function in intact rabbits].
Some data of intact rabbits' cardiovascular system (arterial blood pressure, data of real and maximum function of heart ventricles) were investigated in different seasons of the year. It was revealed, that in winter the cardiovascular system functions with definite degree of overstrain, and in summer these data are on the lower level of the norm. Correlative analysis showed that in summer the degree of synchronization of the function of cardiovascular system drops and this can open wide possibilities for it's adaptation to variable conditions.
