Pacemakers are electronic systems that prevent various cardiac arrhythmias possible that lead to an excessively slow pulse. Progress in microelectronics has led to today's modern systems being able to control up to three chambers of the heart, thus ensuring that the heart's electrical activity is as physiological as possible. Life-threatening cardiac arrhythmias are eliminated utilizing so-called internal defibrillators (ICD), wich also offer a pacemaker function.
Every pacemaker or defibrillator system must be checked at regular intervals (every 6 to 12 months) to detect changes in the battery voltage or on the pacemaker probes in good time or to be able to adapt the programming to the requirements of the patient. The outpatient examination takes about 30 to 45 minutes. The device is painlessly scanned and programmed from the outside using a magnetic head or WIFI system.
