The term supraventricular tachycardia (SVT) is generally used to refer to atrioventricular nodal reentry tachycardia (AVNRT), atrioventricular reciprocating tachycardia (AVRT), and a...
Infants
Manifest signs and symptoms of low cardiac output and congestive heart failure (CHF) with prolonged SVT (>48 hours): tachypnea, retractions, irritability, decreased feeding,...
Short-term treatment goals are to terminate the tachycardia.
Nonpharmacologic vagal maneuvers; for example, ice to the face for 15 to 30 seconds, rectal stimulation, Valsalva,...
Of patients who present in infancy, 30–70% will be asymptomatic by 1 year of age. However, ~1/3 of these patients may experience a reappearance of their tachycardia at an average...

<bold>Figure 33-46</bold> Electrocardiogram during conversion of supraventricular tachycardia to sinus rhythm with administration of adenosine. During tachycardia at a rate of 230 beats/min, there is a normal-appearing QRS complex without a delta wave (no ventricular preexcitation), and there is no distinct P wave. After conversion to sinus rhythm, there is a short PR interval (80 milliseconds) and wide up-sloping QRS complex (90 milliseconds) representing ventricular preexcitation, indicative of...
