[Long-term observation of ventricular extrasystole in children with normal hearts].
Between 1971 and 1980 uniform ventricular extrasystoles, classified as benign, were noticed in 47 children with normal hearts. After a mean observation period of 4.4 years 27 of these children, mean age 10.5 years, could be reexamined. This involved physical examination followed by resting and exercise ECG, 24-hour continuous ECG and echocardiography. Of the 27 children, 18 still had extrasystoles having the same morphological characteristics and identical behaviour under exercise as those seen on first examination. Nine children were free of extrasystoles in all ECG examinations. In none of the 27 children were there any complaints between the first and the second examination or signs of degeneration of the extrasystoles into threatening dysrhythmias.


CONCLUSIONS
Uniform extrasystoles disappearing or decreasing on exercise in otherwise healthy children require no treatment even when occurring frequently and persisting over years.
