Adenosine for suppression of paroxysmal supraventricular tachycardia in a newborn infant. First case in Mexico

We present the case of a 20-day old baby who was admitted with orthodromic supraventricular reentry tachycardia with a heart-rate of 300/minute. Suppression of the arrhythmia was tried with vagal maneuvers and digoxin. On failure to control the heart rate, a 0.05 mg/kg intravenous bolus of adenosine...

Summary:We present the case of a 20-day old baby who was admitted with orthodromic supraventricular reentry tachycardia with a heart-rate of 300/minute. Suppression of the arrhythmia was tried with vagal maneuvers and digoxin. On failure to control the heart rate, a 0.05 mg/kg intravenous bolus of adenosine was given, with immediate response and subsequent normal heart rate and rhythm. In the following year he has been adequately controlled with oral digoxin. This is the first pediatric patient treated with adenosine in Mexico. Even though experience elsewhere in this age group is also limited, the properties of adenosine make it a valuable first-choice drug for the control of paroxysmal supraventricular tachycardia.
