[The pathomorphologic characteristics of the arrhythmogenic heart].

UNLABELLED: A complex pathomorphological study was carried out of 80 hearts from patients who died of cardiosclerosis with marked heart rhythm disorders and 20 control cases with the purpose of assessment of the criteria of diagnosis of the arrhythmogenic heart.

METHODS USED: postmortal coronarography and cardioventriculography, microdissection, WHO standard anatomical method, morphometric histological, histochemical and histotopographic methods. The author established pathomorphological criteria of diagnosis of the arrhythmogenic heart including a separate construction with prevailing changes of the right ventricle, fibro- and lipomatosis of the myocardium, extensive coronary obstruction forming ischemia foci in the conduction system zones which are the site of formation of arrhythmogenic substances.
