PHYSIOLOGICAL ASPECTS OF THE ECG

Abstract

This research paper examines the key physiological mechanisms underlying the formation of the electrocardiogram. It analyzes the characteristics of cardiomyocyte action potentials, the role of the cardiac conduction system (sinus node, atrioventricular node, His bundle, and Purkinje fibers), the relationship between electrical processes and the phases of cardiac circulation, and the patterns of the appearance of the main ECG elements—waves, segments, and intervals
