A 35-year-old woman, diagnosed with polymyositis about 5 years before was admitted to the authors' clinics with syncope attack due to complete atrioventricular (AV) block. Progression of left bundle branch block to complete AV block despite all immune-suppressive treatment, and rarity of this complication in patients with polymyositis prompted the authors to report this case.
