title: Third-degree heart block developing in an HLA-B27-positive individual with a family history of ankylosing spondylitis.
abstract: A case of complete heart block is presented in a patient whose brothers were known to have ankylosing spondylitis. Uveitis and sacro-iliitis are well recognised among HLA-B27-positive siblings of ankylosing spondylitis. However, heart block is a rare occurrence as a sole presentation in siblings of patients with ankylosing spondylitis.
