Complete heart block in an Inuit family.
An Inuit family from Cape Dorset, Northwest Territories is described; six had documented complete heart block, one high grade atrioventricular block, one bi- or trifascicular block and all suffered syncope. One other member received a pacemaker for unknown reasons. Two of three middle-aged relatives had minor conduction abnormalities. All younger family members who were examined had no conduction problems. This suggests a heritable form of adult onset complete heart block, the largest series reported in the English literature.
