Neonatal supraventricular tachycardia (original) (raw)

Neonatal supraventricular tachycardia (SVT) is a significant arrhythmia often misdiagnosed in infants. This report presents the clinical profiles, electrocardiographic (ECG) findings, and treatment responses of four neonates diagnosed with SVT. Although initial misdiagnosis occurred with three infants referred for pneumonia, all presented with heart rates exceeding 200 bpm and signs of congestive cardiac failure. Following synchronized direct current (DC) cardioversion, three patients were treated with digoxin, while one suffered from recurrence linked to myocarditis. SVT in infants generally has a favorable prognosis, contingent upon the presence of underlying heart conditions.
