Atrioventricular Block as a Severe and Unusual Extra-Articular Presentation of Rheumatoid Arthritis: A Comprehensive Case Report and Literature Review

Background: Rheumatoid arthritis is a systemic condition impacting not only joints but also various organs, with potential life-threatening consequences, particularly involving the heart. Pericardial damage is a prevalent cardiovascular manifestation that generally responds well to anti-inflammatory interventions. While atrioventricular block in RA is uncommon, it remains a possibility and poses a threat to vital prognosis in the absence of proper treatment. Case Presentation: We present the case of a young female patient with a 23-year history of rheumatoid arthritis, experiencing recurrent syncope episodes associated with complete atrioventricular block. The severity of the condition necessitated the implantation of a dual-chamber pacemaker. Conclusions This case holds significance due to the rarity of atrioventricular block in rheumatoid arthritis, its complex pathophysiology, and the essential reliance on cardiac stimulation for treatment, as anti-inflammatory interventions show limited efficacy in this particular scenario.
