title: [Fetal arrhythmias--new immunologic studies and results].
abstract: The etiology of fetal arrhythmias is still unknown. We therefore did a research for immunologic causes: antimyolemmal antibodies (AMLA) in mothers and umbilical cord serum resulting from secondary immunopathogenesis caused by myocarditis of the mother. Is there a correlation between immunological and clinical findings giving a possible explanation for fetal arrhythmias? In 21 cases mothers and umbilical cord serum was investigated for AMLA; 16 with fetal atrial premature beats, 4 with fetal tachycardia and 1 with fetal bradyarrhythmia. From 16 mothers with fetal atrial premature beats had 12 AMLA, from these were in 4 cases in the umbilical cord serum AMLA. In 4 cases of fetal tachycardia we found in 1 case AMLA in mothers and umbilical cord serum. In the other 3 cases accessory pathways have been the cause for tachycardia. From 19 healthy persons were found in 3 cases AMLA in mothers serum, umbilical cord serum was negative.
