[Macro- and microscopic anatomy of the heart conduction system in myocardial infarction].
Morphological and morphometric examinations of the cardiac conduction system (CCS) of subjects who had died in different periods of acute myocardial infarction in the presence of atrioventricular block versus those without conduction disturbances have indicated that the severity of circulatory disorders leading to destructive processes in the ischemic myocardium, as well as involutional processes in its autonomic nerve terminals are essential in the development of functional abnormalities in CCS in myocardial infarction. The more profound the dysfunction of CCS is, the closer it is to the myocardial alteration foci. The altered CCS with the block recorded should be interpreted as its impact of ischemia in the presence of fibrosis and calcinosis of ventricular septal structures.
