title: [Quantitative evaluation of participation of the cardiac and vascular components in arterial pressure changes].
abstract: Under the effect of adrenaline upon the circulation system, vascular components of the blood pressure (BP) was shown to provide 75% of the maximal rise of the BP and the cardiac component--25%, whereas in response to noradrenaline the values were 62% and 38%, resp., in cats. In further development of systemic responses the role of cardiac component is enhanced whereas the role of vascular component becomes limited. Participation of the vascular component alone in systemic shift induced with catecholamines, under conditions of stabilised cardiac output, decreases the duration of the BP rise, whereas a combined rise of peripheral resistance and cardiac output in natural circulation provides an elongation of the BP changes.
