Objective Preference for epicardial stimulation in children weighing less than 10 kg is obvious. The disadvantages include a higher threshold of stimulation and as a result a shorter service of the pacemaker.

Methods Since 2007, 54 implants of cardiac pacemaker for children have been carried out in our center. The minimum age was 3 days, the maximum age was 17 years. In 21 cases, an epicardial stimulation system was used by CapSure Epi Medtronic electrodes. In 5 patients weighing less than 10 kg, the possibility of epicardial implantation was questionable because of the pronounced adhesion process due to previous cardiac surgery, so Electrodes Select Sequre Medtronic were used for endocardial stimulation for complete atrioventricular blockade.

Results In 3 cases, a 2-chamber cardiac pacemaker was implanted. In one case, a single-chamber system was established because of the difficulties with implantation of the atrial electrode. The growth of the stimulation threshold (maximal to 2V was observed in one patient, the greatest period of observation of patients was 7. The blood flow in the subclavian vein was preserved in all patients.

Summary If difficulties of epicardial stimulation occur in patients weighing less than 10 kg, endocardial implantation of the pacemaker is possible with a suitable effect.
