[Implantation of a cardiac pacemaker in the 25th week of pregnancy in acquired 3d degree AV-block].

It is well documented, that bradycardiac electrical heart activity disturbances occur very rarely in women of reproductive age. Therapy is in fact redundant in congenital AV-block. However, acquired AV-block in pregnancy constitutes a risk for both mother and child. In the following case, we report on an acquired third-degree AV-block, which worsened during the pregnancy from N.Y.H.A stage I to stage III, and hence required the implantation of a pacemaker during pregnancy.
