РЕГУЛЯЦИЯ СЕРДЕЧНОЙ ДЕЯТЕЛЬНОСТИ

Аннотация

This article examines the fundamental mechanisms regulating human cardiac activity. It describes the neural, humoral, and local factors that coordinate cardiac function with the body's needs. The role of the sympathetic and parasympathetic divisions of the autonomic nervous system, hormonal influences, and intracardiac self-regulation mechanisms are analyzed in detail. Current concepts regarding the central and peripheral components of heart rhythm, heart rate, and contraction force are presented. The importance of coordinated functioning of all regulatory systems for maintaining homeostasis and adapting to physical exertion and stressful situations is emphasized. Keywords: heart, regulation, autonomic nervous system, humoral factors, automaticity, adrenaline, parasympathetic system, cardiac conduction system, homeostasis.
