Out of 100 patients with chronic heart block 16 had one or more autoimmune disorders-namely, vitiligo (5,) hypothyroidism (4), Graves's disease (1), pernicious anaemia (2), and diabetes mellitus (9). All these disorders occurred with greater frequency than normal and were more prevalent than in a group of hospital inpatients of comparable age. Autoantibodies were not increased. We suggest that among patients with idiopathic heart block there is a subgroup with multiple autoimmune disorders.
