title: [Congenital heart block and pacemaker implantation (author's transl)].
abstract: A six years old boy was sent to our service due to a loss of conscience spell. He had no preceding history E.K.G. showed a complete A-V block. Laboratory findings were within normal limits. Cardiac catheterism was performed and it ruled out any antomic abnormality, making evident a good contraction ability. To decide pacemaker implantation we evaluted: 1. That cardiac frequency was not increased by exercise neither by action of pharmacologyc agents (atropine, insoproterenol).-2. The existence of wide and bizarre QRS ocmplex.-3. And dizziness spels. The patient has been controlled during the past two years. Parasistolia has appeared, not showing modification till today.
