[Pregnancy in women with atrioventricular block. 13 cases]

Thirteen women aged between 18 and 37 years and suffering from atrio-ventricular block had 36 pregnancies. Foetal prognosis was excellent and the pregnancy quite unaffected by the block in 9 cases. In 4 women, Stokes-Adams attacks occurred. In one case from some time ago therapeutic abortion was necessary. Temporary pacing at the time of delivery was used in one case and a permanent pacemaker in one patient. The problems posed by the insertion of a pacemaker in a woman of childbearing age are discussed.
