title: [Perinatal Presentation and Complicated Course of a Multifocal Atrial Tachycardia].
abstract: We report a male newborn who became symptomatic with supraventricular tachycardia on the first day of life. Neither adenosine nor electric cardioversion could terminate the tachycardia, therefore intravenous esmolol (β-receptor blocker) was initiated. Inspite of subsequent administration of various antiarrhythmic medications in increasingly higher doses, repeated supraventricular tachycardic episodes occurred. The electrocardiogram showed typical findings of a multifocal atrial tachycardia as the underlying cause. When tachycardic episodes occurred, they also presented as atrial flutter at 460 bpm and a 2:1 block. Finally, high dosage of amiodarone (10 mg/kgbw/d) led to continuous control of the heart rate without tachycardic episodes. To date our patient is mostly in sinus rhythm but without tachycardic episodes and doing well.
