For the past thirteen years, pacemaker implantation has been performed to 21 patients in our clinic. The patients were under 15 years of age, consisting of 7 females and 14 males. The mean age at the time of operation was 7 years old. Thirty-nine pulse generators in total were implanted. Seventeen cases (81%) were using a myocardial lead. An endocardial lead has been used in four cases over 13 years of age. The indications for pacemaker implantation were 4 cases of congenital heart block, 2 cases of sick sinus syndrome, 1 case of paroxysmal atrial tachycardia and 14 cases of postoperative complete heart block. Because battery exhaustion was noted in 18 cases, new pacemakers were implanted. Complications included 5 cases of threshold elevation, 3 cases of lead fracture, 1 case of twiddler's syndrome and 1 case of left ventricular rupture by a screw type lead et al. They were managed properly. To prevent the threshold elevation, it is important to measure the threshold of a pacemaker lead at the time of primary implantation as well as at the time of generator change. Seven cases died after pacemaker implantation. A pacemaker related death was 1 case in which the patient died from pacemaker battery failure. Fourteen patients are presently alive (67%). All cases, including 8 surgical heart blocks, are doing well, enjoying an active life. The rate of complication decreased with growth.
