The management of supraventricular tachycardia (SVT) in infants is somewhat controversial since numerous methods of treatment are effective. Regardless of the treatment chosen, it is important to quickly stop the tachycardia in neonates with SVT because they may suddenly become hemodynamically unstable.. Seventeen episodes of SVT treated with intravenous ATP are studied in 3 newborns (two were preterm infants: 30 and 34 weeks of pregnancy). Ages at presentation ranged from 2 to 27 days.. ATP is effective in all episodes of SVT, with a mean intravenous doses between 0.10 and 0.50 mg/kg/dose. All patients showed short sinus arrest after ATP. No adverse side effects or hemodynamics changes occurred after ATP administration.. ATP is a safe and reliable antiarrhythmic in neonatal period, including prematurity. We reviewed the experience in ATP management of SVT, mainly in pediatric population.

A variety of acute supraventricular tachycardias may be encountered. In many instances the therapies for these rhythm disturbances overlap, but a rational approach to individual disturbances should be based on an understanding of the anatomy and physiology involved in the individual dysrhythmia. Numerous investigative approaches are underway at present, especially with regard to interruption of arrhythmia pathways by electroshock therapy or surgical therapy. In addition, pacing overdrive may be very effective, especially in patients with reentrant arrhythmias.

Nine infants with episodic or continuous chaotic atrial rhythm (CAR) are presented. In addition to 3 or more different P-wave contours, atrial rates greater than 100 per minute, variable PP, RR, and PR intervals, and a discrete isoelectric baseline, findings included atrial rates that varied from a low of 50 to 120 to a high of 140 to 270 per minute, ventricular rates that varied from a low of 40 to 50 to a high of 180 to 270 per minute, and periodic sinus arrest with junctional escape rhythm. Except for the arrhythmia, all had a normal cardiac examination, ECG, chest x-ray film, and echocardiogram. Six infants were otherwise normal; one had an orbital rhabdomyosarcoma; one had neonatal asphyxia; and one had respiratory distress, bronchopulmonary dysplasia, and an intraventricular cerebral hemorrhage. The CAR persisted from 3 days to 20 months; it spontaneously reverted to normal sinus rhythm in 8 infants and persists in 1 infant at age 7 months. Digoxin (4 patients), propranolol hydrochloride (3 patients), quinidine sulfate (2 patients), and lidocaine (1 patient) did not alter the CAR. No patient had heart failure secondary to the CAR, although three also had episodes of sustained atrial tachycardia, which while present caused heart failure. All patients are functioning normally at home and have normal findings on cardiac examination and have normal ECGs at ages 3 to 38 months. Seven are in normal sinus rhythm, one has rare atrial premature contractions, and one has persistent CAR. We conclude that specific treatment was not necessary in these infants with CAR, except in those with associated sustained atrial tachycardia, which itself may cause heart failure.

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 ATP in less than 1 minute. Digitalis, however, took as long as 2 hours; it was therefore excluded as the drug of first choice in emergencies, and is better suited for treating patients with poor hemodynamics. Side effects with ATP are common but short-lived. With verapamil, side effects are rare, but may be serious if certain contraindications are not taken into account. Digitalis in the dose used in this trial rarely produced side effects. We conclude that ATP or verapamil is the drug of first choice for quick termination of PSVT in infancy.
