Management of paroxysmal supraventricular tachycardia in the first month of life

Abstract

Introduction: Paroxysmal supraventricular tachycardia
(PSVT) is the most frequent arrhythmia in pediatrics after
extrasystoles. Most of the times, it is well tolerated, but it
must be kept in mind that there is risk of heart failure if the
tachycardia is prolonged over time. Thus, it is important to
know the symptoms, diagnosis and acute and chronic management
of these patients.
Clinical cases:We present four cases of PSVT in infants
under one month who have been treated in our center over
the last 4 years. In our series, predominance of gender has
not been observed. All the cases occurred prior to 1 months
of life, two of which were associated to congenital heart disease
and one had heart failure. After chronic treatment was
established, there have been no recurrences up to date.
Comments: Although rhythm disorders are relatively rare
in children, its knowledge is a fundamental subject in the pediatric
practice. In addition, it is very useful to have unified action
protocols in our services for the treatment of these disorders.
