Paroxysmal tachycardia in infancy.

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

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...

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...

Paroxysmal tachycardia in a child showing Stokes-Adam and Wolff-Parkinson-White syndromes.

Paroxysmal tachycardia in infancy may be accompanied, as in the adult, by some disturbance giving rise to pallor, restlessness, dyspnoea, weakness and usually cardiac insufficiency and decompensation. A labile autonomic nervous system makes infants particularly vulnerable to paroxysmal forms of tachycardia. Exactly what it is that starts this disorder or rhythm is frequently obscure and consequ...

Paroxysmal tachycardia in infancy.

Since Bristowe (1887) first described a series of cases of ' recurrent palpitation of extreme rapidity in persons otherwise healthy', paroxysmal tachycardia in adults has become a well-known condition. In children the condition has been considered rare. Taran and Jennings (1937) in a review of the literature found only 52 cases under the age of 15 from 1892 to 1935, to which Johnson (1940) adde...
