[Ultrastructure of the Purkinje cells in the subendocardium and pseudo-tendons of the left ventricle in dogs with experimental infarct complicated by fibrillation].
Ultrastructural changes of Purkinje cells located on the periphery of the cardiac conductive system (subendocardium and false tendons) were studied in dogs in the presence of ventricular fibrillation developed in 30 minutes after coronary artery ligation. Ventricular fibrillation at the early stages of experimental myocardial infarction was invariably associated with the development of multiple ultrastructural lesions in the conductive Purkinje cells of subendocardium and false tendons. These changes are without any doubt important for the pathogenesis of ventricular fibrillation in myocardial infarction and they possibly take place in cases of sudden cardiac death.
