Cardiac pacing in children and young adults

Pacemakers are being used with increasing frequency in children. New pacemakers are smaller, more sophisticated, can be programmed, have output telemetry, are more reliable, and are longer lasting. Implant techniques have been modified, so that they are less traumatic to the patient and result in better electrical measurements. Transvenous implants seem to be the preferred method in children who weigh 13.5 kg or more. Physiologic dual-chamber pacemakers make the patients feel better. The time between hospitalizations for pacemaker replacements or revisions has increased from 14.7 months in 1974 to 22 months in this study.
