[Multifocal (chaotic) atrial tachycardia in infancy].
A newborn baby shows atrial tachycardia and gets into cardiac failure by atrial fibrillation at 12 weeks of age. With digoxin and chinidin spontaneous conversion to multifocal atrial tachycardia occurs. Treatment with additional propranolol leads to atrial fibrillation and paroxysmal atrial tachycardia with block. When chinidin was discontinued atrial flutter occurred. With a maintenance therapy with digoxin and chinidin the baby remained asymptomatic, and sinusrhythm occurred at 6 months of age. At 9 months chinidin was discontinued. At 14 months of age, the child is well and in sinusrhythm with a maintenance digoxin therapy. This seems to be the third described case of multifocal atrial tachycardia in infancy.
