[Treatment of heart-rhythm disorders in infancy and childhood]

According to own experiences and after a review of the literature a survey of therapy of cardiac arrhythmias in infancy and childhood is given. In this age group most of the occurring cardiac arrhythmias are harmless and pass without serious circulatory disturbances. Therefore in these cases no specific treatment is necessary, except of course the treatment and management of the disease which is causing the arrythmia. This report is concerned more detailed with the therapy of rhythm disturbances which are life threatening or will become fatal if they continue untreated for a longer period. In spite of the therapeutic recommendations given we are aware of the fact that it is impossible to predict the success of therapy. This turned out to be so especially in the case of tachycardias. The difficulties in long-term management of postoperative heart block are mentioned. Antiarrhythmic drugs, their indications, efficacy, side-effects and contraindications are listed in separate tables ("FdM-Tabellen für die Praxis" Nr. 30/1975, Fortschr. Med. 93, 30: 1447, 1975).
