Redundant pacing in a child.
A 4-year-old boy with congenital complete atrioventricular block (CCAVB) and pacemaker (PM) dependency, received a redundant pacemaker. Two separate leads were implanted in the right ventricle, and connected to a dual chamber PM. The two pacing channels were both programmed so that each lead could compensate for the other in case of threshold elevation. The follow-up was uneventful despite exit block on one of the leads.
