New onset left bundle branch block with right axis deviation in a patient with Wegener's granulomatosis

Left bundle branch block (LBBB) is usually associated with a normal axis or left axis deviation (LAD). When it is seen in association with right axis deviation (RAD) it is felt to be a marker of diffuse advanced myocardial disease. We report a case of new onset LBBB with RAD in a patient with Wegener's granulomatosis who had an otherwise functionally and structurally normal heart. To our knowledge, this is the first case report of LBBB with RAD without severe cardiomyopathy, as well as the first case report of new onset LBBB as a result of Wegener's granulomatosis.
