title: [A case of intrauterine fetal retardation with polycythemia in a patient with a pacemaker].
abstract: A case of intrauterine fetal growth retardation with polycythemia is reported on a newborn whose mother was treated five years before pregnancy by an artificial external fixed-rate pacemaker because of complete atrioventricular block with right bundle-branch block and Adams-Stokes syndrome. Obviously fixed-rate pacemaker does not meet all necessities of pregnancy. Therefore in young women who wish to have children only demand pacemaker with programmable frequency are supposed to be used. They may be better for the requirements of systemic and uterine circulation in pregnancy.
