title: Familial congenital heart block and hydrops fetalis.
abstract: Two siblings were born with congenital heart block, and one suffered from severe hydrops fetalis, although maintaining a higher heart rate than the other. The association of hydrops fetalis with disorders of cardiac rhythm is unlikely to be simply a manifestation of congestive cardiac failure in the fetus.
