Pacemaker implantation refers to the fitting of devices to regulate heart function. They include pacemakers, defibrillators and resynchronisation systems. These devices can be implanted in young patients with congenital heart defects or in older patients with irregular heartbeat. The Swiss Atlas of Healthcare contains analyses on the frequency of pacemaker implantations in total in inpatient settings, separate analyses on resynchronisation pacemakers and resynchronisation defibrillators, as well as total procedures in outpatient settings and overall (outpatient and inpatient).
