[Antibradycardia therapy : Indication and implementation].

: Pacemaker therapy (PMT) in grown-up congenital heart disease (GUCH) must meet the demands of a young, dynamic and heterogeneous group of patients. The duration of the therapy has to be planned for several decades and should be accompanied by an invasive procedure at the very least. Most of the patients enter adulthood with their pacemaker (PM) already implanted; for others the indications can be derived from the published guidelines for GUCH and PMT, but need to be adjusted to the individual situation of the patient. Depending on the underlying heart disease the decision on the use of either an epimyocardial or a transvenous PM system has to be made. Both electrodes and PM should correspond to the latest technical developments to optimally adapt to the patients' multiple requirements. In the case of PM system revisions abandoned leads should be removed and vascular stenosis or occlusions cleared to be prepared for later revisions. During any cardiac surgery epimyocardial PM systems should be checked against the patient's needs and expanded or revised accordingly. Epimyocardial resynchronization systems in particular offer more opportunities for compensating for cardiac dysfunction with greater reliability using a second ventricular lead. The PMT is an essential part of the medical treatment for many patients with GUCH and contributes significantly to the well-being and quality of life. Against this background, a competent and consequent follow-up regime requires experienced physicians. An integrated telemetric monitoring system for the PM has proven valuable and supports the early recognition of cardiac arrhythmia.
