Supraventricular tachycardia in infancy and childhood.

Management of supraventricular tachycardia in infancy and childhood.

Supraventricular tachycardia (SVT) in infancy and early childhood is dangerous and potentially fatal, but if it is diagnosed early and treated appropriately it has an excellent prognosis. Until a few years ago the recommended initial treatment was usually either digoxin or cardioversion. Digoxin, however, was often ineffective and cardioversion required anesthesia or sedation and was not easily...

Concealed pre-excitation causing paroxysmal reciprocating atrioventricular tachycardia in infancy.

We report 3 infants with Wolff-Parkinson-White (WPW) syndrome who presented with life-threatening paroxysmal reciprocating atrioventricular tachycardia in their first month of life. The diagnosis was confirmed by electrophysiological studies at ages 2--4 years, but the characteristic ECG of pre-excitation has not been shown in one patient and was first recorded at 2 and 3 years in the other two...

A case of paroxysmal supraventricular tachycardia in infancy treated with procaine amide.

Treatment of paroxysmal supraventricular tachycardia in infancy with digitalis, adenosine-5'-triphosphate, and verapamil: a comparative study.

The treatment of paroxysmal supraventricular tachycardia (PSVT) in infancy with digitalis, adenosine triphosphate (ATP) and verapamil is reported. Treatment was successful in about 90% of the patients treated with ATP and verapamil and in 61--71% of the patients treated with digitalis (Lanatoside C). Verapamil terminated the tachycardia within 2 minutes of administration in most instances and A...

Cardiovascular collapse after verapamil in supraventricular tachycardia.

Five babies who presented with supraventricular tachycardia were treated with verapamil intravenously. All developed severe hypotension and two died. Verapamil should not be used in the initial management of supraventricular tachycardia in neonates.
