title: Pacing in children and adolescents.
abstract: Sixty patients aged 5-16 years underwent implantation of permanent pacemaker and were followed up for 3-11 years. All these patients presented with syncope or symptomatic bradyarrhythmias; two also had congestive cardiac failure in addition, which was ameliorated by pacemaker implantation. A majority of the patients (48) had congenital complete heart block. 8 patients presented with sick sinus syndrome; 4 patients presented with post operative chronic complete heart block. Transvenous endocardial electrode was used in 54 cases and epicardial pacing was done in 6 cases. A majority (55) of the patients received VVI pacemakers; AV sequential pacemakers were implanted in 5 cases. On follow up, the children returned to normal activity and their psychological well being was striking. Reoperation had to be done in 35 cases, a majority being due to over stretching of electrodes (15) and battery exhaustion (12). Two patients died, one due to bacterial endocarditis and the other succumbed to sudden death during vigorous physical activity. Major problems of pacing in children are that veins are often too thin and delicate for electrode insertion, and of the child's growth that stretches the lead system. The problems of pulse generator size and longevity have been partly overcome by introduction of newer models that are small and programmable.
