Abstract:
Using the method of arterial piezopulsometry, statistical and spectral analyzes of variable parameters (VmaxPP and TNN) of pulse waves of blood pressure in patients aged 18 to 85 years were performed. The individual characteristics of the autonomous (vegetative and neuroendocrine) regulation of the muscular effectors (ME) of the cardiovascular system (CVS) in an elderly man (75 years old) and a young woman (20 years old) were estimated with high accuracy. These data, as well as the results of a comparative study of patients of different ages, made it possible to identify a certain pattern of directed change in the sympathoadrenal regulation of ME CVS in human ontogenesis. It is concluded that in the course of their lives, people undergo a restructuring of the physiological mechanism of the autonomous regulation of their ME CVS, aimed at replacing short-term sympathetic regulation in young people with more effective and more stable regulation by humoral catecholamines in elderly.

Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
