A Case of Lupus Erythematodes with ArrhythmiasA Complete Morphological Study of the Conduction System

摘要

The conduction system of a case of systemic lupus erythematodes with incomplete atrioventricular block and atrial flutter was studied histopathologically with complete serial sectioning. It was highly suggestive that incomplete interruption of the atrio-AV nodal junction by fibrosis based on connective tissue change of systemic lupus erythematodes corresponded to the AV block and focal hemorrhage into the internodal tract was related to the terminal atrial flutter.
