title: [Paroxysmal Hisian tachycardia and familial sarcoidosis].
abstract: We report a His-bundle tachycardia in a 6 year-old patient without evidence of heart disease. Diagnosis and follow-up were assessed by exercise stress testing and repeated long-term electrocardiographic recording. As sarcoidosis was present in the mother and the aunt, this condition was discussed in this child also. However, since there is no absolute proof for this disease, the hypothesis of an antenatal injury of the bundle of His was discussed: this could be secondary to the transplacental transfer of abnormal maternal antibodies, as frequently observed in women with clinical or biologic evidence of connective tissue disease.
