Electrocardiographs Abnormalities in a Family with Generalized Lentigo

Abstract

THE existence of familial cardiac-conduction abnormalities has been known since a report by Morquio1 at the turn of the century. A more recent report reviewed this subject and described 3 generations of a family with conduction disorders.2 This communication reports a family of 4, 3 members of which have a pigmentary disorder attended by electrocardiographic changes, 2 having patterns resembling inferior myocardial infarction. None of the subjects have had cardiovascular symptoms at any time.The family came to our attention when the propositus, M.McD., was referred to the Pediatric Heart Clinic of the Boston City Hospital by a school physician . . .
