Core Tip

Core Tip: Anti-SSA/Ro antibodies may affect the conduction system in adults, leading to atrioventricular block, even complete atrioventricular block (CAVB). Anti-SSA/Ro antibody-positive autoimmune myocarditis (AM) complicated with CAVB is rarely reported, and the pathogenesis is not clear. Cases requiring permanent pacemaker implantation are extremely rare. This paper reports a patient who had anti-SSA/Ro antibody-positive AM complicated with CAVB, and immunosuppressive therapy did not change the outcome of permanent pacemaker implantation.
