Spatial characteristics chambers of the heart of experimental animals with different types of vegetative regulation
The purpose of this work - to study spatial parameters intact chambers of the heart of experimental animals with different types of vegetative regulation. To achieve this aim used electrocardiographic, morphometric and statistical methods. Found that planimetric and volumetric parameters intact parts of the heart muscle laboratory mature male albino rats are in a certain range and depend on the type of vegetative regulation. Revealed that the area endocardial surface of the left ventricle in white rats normotonical equal (145,5±2,1) mm2, animals with a predominance vagotonical effects on the heart - (139,3±2,1) mm?2, in rats sympatotonic - (153,1±1,8) mm2, and the same parameter reached under the right ventricle (176,6±1,8) mm2, (167,9±1,8) mm2 and (184,5±2,4 ) mm2. Spatial cardio parameters parts of the heart muscle dominated the hearts of the predominant influence of the sympathetic division of the autonomic nervous system to the heart. Relationship between planimetric parameters of atria intact heart is the most altered were prevailing at vagotonical effects on the heart muscle. Detailed learning space cardio parameters intact parts of heart, depending on the options for autonomic regulation significantly enhance the ability of diagnostics, correction, prevention and prognosis of various cardiopathology.
