• Abstract:

  Introduction: Supraventricular tachycardia occurs in an incidence of 16 to 100 thousand newborns and there is a good prognosis if the diagnosis is made early and the oral treatment is adequate. The clinical status is non-specific and varies among age groups, with signs and symptoms of irritability to palpitation. Early diagnosis and appropriate treatment are essential because of the risk of possible progression to heart failure after a variable period. Methodology: Retrospective analysis of the medicalrecord of 2 patients with neonatal supraventricular tachycardia of our pediatric cardiology department. Results: The supraventricular tachycardia is the arrhythmia in common to these two patients of the neonatal age group shown in this case report. The first patient had a better and faster response to the proposed clinical treatment, compared to the second, showing that the early diagnosis is associated with a better prognosis. Conclusion: 1) Sepsis is a differential diagnosis of supraventricular tachycardia in neonates. 2) The vagal maneuver can be used to reverse the clinical condition, and if ineffective, in stable patients, Adenosine can be used successfully. 3) The prognosis is good if the diagnosis is made early. 4) If supraventricular tachycardia is not treated or diagnosed, it may evolve to a tachycardiomyopathy and cardiogenic shock.
