[Treatment of a severe temporary heart arrhythmia by transvenous pacing in a neonate (author's transl)].

Report of the treatment of a neonate with bradycardia (cardiac dysrhythmia) with an external transvenous pacemaker. At the age of 19 days the child developed repeated and critical dysrhythmias which made intubation and artificial respiration necessary. Conservative therapy attempts were without success. A stimulation-catheter was inserted through the internal jugularis vein and an external Demand-pacemaker connected to it. The stimulation-catheter was disconnected after 12 days with the complete cessation of the initial frequent bradycardia episodes. The cause of the cardiac dysrhythmia could not be clearly found. Tachycardia-bradycardia syndrome and Phase-IV block are being discussed.
