[Atrial tachycardia with atrio-ventricular block in infancy and childhood (author's transl)].

Atrial tachycardia with atrio-ventricular block is a very rare arrhythmia in infancy and childhood. We saw ten patients between 3 days and fifteen years old. Six of them had a congenital heart disease, in four cases we could'nt find any cardiac or extracardiac illness. In every case digitalis intoxication was excluded. Clinical findings, electrocardiographic features, therapy and prognosis are reported.
