I am 20 wks pregnant, the baby was diagnosed with fetal heart block. I don't have any underlying conditions, we were told this was random and there is no cure. If the baby makes it to term, it would need a pacemaker as soon as it is born. Has anybody been through a similar diagnosis or know of somebody else who has? What are the chances of survival? Can a baby with a pacemaker from birth grow into a healthy adulthood? Does anybody know of any adults who have had pacemakers since birth and are able to lead normal lives?
