High-grade atrioventricular heart block in an adult with systemic lupus erythematosus: the association of nuclear RNP (U1 RNP) antibodies, a case report, and review of the literature.
High-grade atrioventricular heart block (HGAVB) occurring as a manifestation of systemic lupus erythematosus is an exceedingly rare event. We describe a patient with HGAVB who had myositis and antibodies to nuclear RNP (previously associated with myocarditis). A review of the literature on HGAVB associated with systemic lupus erythematosus is also presented.
