Systemic sclerosis is a complex disease that affects the connective tissue, the vascular system and the immune system. It typically produces skin and organ fibrosis. Cardiac bundle branch blocks and fascicular blocks occur in 25-75% of the cases and were found to be independent predictors of mortality. Second and third degree atrioventricular block are very rare. We present the case of a 47 year-old female with diagnosis of systemic sclerosis, presented with syncope secondary to complete atrioventricular block requiring permanent pacemaker implantation.
