[Extrasystole in the neonatal period].
We investigated the clinical course in 35 healthy newborn with premature beats and studied the literature with regard to their frequency, pathogenesis, and therapy with the following results: Investigations with continuous monitoring or long-term ECG registration show a frequency of 7-25%. In literature, almost one-fourth, in our patients one-half of the newborn have ventricular premature beats. These will probably disappear later than atrial premature beats, but their prognosis is not worse. The premature beats of newborn are often complex (blocked or aberrant conduction, bigeminus, tachycardia). Atrial flutter is sometimes associated. In one-half of cases they disappear spontaneously during the first month of life. However, they lasted for longer than 4 months in 7 out of 35 infants. The disorder increased after birth in 2 children, which is unusual. Therapy was indicated if there were signs of heart failure, frequent or increasing rate of tachycardia or atrial flutter. Premature beats do not indicate primary operative delivery. Immaturity of the central and autonomous nervous system and of the conduction-tissue of the heart may be the reason for frequent perinatal premature beats.
