“…[7] For conduction disorders, several mechanisms are incriminated and may contribute to development of several degrees of AV Blocks, like ischemia, inflammation, or destruction of conductive tissue by rheumatoid nodules. [7] Our patient had normal inflammatory tests, no previous coronary disease, High-sensitivity Troponine T and electrolytes were within normal limits, so coronary disease or ongoing inflammation, were unlikely. Destructive invasion of the conductive tissue by a rheumatoid nodule is the most likely, because of the obvious presence of calcified rheumatoid arteritis, embedded in the basal site of inter ventricular septum, and macroscopically visible in transthoracic echocardiography.…”
