Abstract:
Objective To explore the clinical features and prognosis of arrhythmia in newborn infants.Methods Eighty children with arrhythmia were diagnosed by physical examination and electrocardiogram monitoring in author's hospital from Jan.2004 to Dec.2006.Their clinical features and 24-hour dynamic electrocardiogram were analyzed at the acute stage and followed up.Results Out of 80 cases of arrhythimics,52 cases were boys and 28 cases were girls,with an average age of 4 days on diagnosis of arrhythmias.Forty-five neonates presented with supraventricular arrhythmia,accounting for 56.3%.Their clinical presentations were atypical,and the hypoxia,infection,electrolyte disturbances and metabolic disorders were the main causes of the arrhythmias.After supportive and anti-arrhythmia treatment,18 cases of arrhythmias disappeared of 25 children with premature atrial beats;10 cases of 21 children with premature ventricular beats were cured,2 cases of 4 children with ventricular tachycardia,1 case died;2 cases of 3 children with supraventricular tachycardia didn't occure;3 cases of 5 with atrio-ventricular block were cured.The prognosis was better in supraventricular arrhythmias than that in ventricular and other arrhythmias at discharge.At the follow-up of(1.2?0.7)years,there were no differences in rates of recovery between supraventricular arrhythmias and ventricular arrhythmias.Conclusions Supraventricular arrhythmia was the most common type of arrhythmias in neonates.Most of the arrhythmia in neonates might be functional and could recover without treatment.Supraventricular arrhythmia usually had better prognosis in acute period.Only a few neonates with severe arrhythmia need anti-arrhythmias treatment.
