title: Complete atrioventricular block as initial manifestation of systemic lupus erythematosus.
abstract: Only a few cases of complete atrioventricular block (AVB) in adult lupus patients have been previously described, but only one as the initial manifestation. A 19-year-old woman who presented with seizures and loss of consciousness, was diagnosed with complete ABV and underwent pacemaker placement. Over the next weeks she developed serositis, joint, cutaneous, and renal involvement; positive antinuclear antibodies and high anti-SSA/Ro titers. This is the second case with AVB as a feature of SLE at onset. A review of previous complete AVB cases of adult SLE patients is presented.
