Supraventricular tachyarrhythmias of the neonatal period are alterations in the heart rhythm that produce an abnormal increase in the heart rate of the newborn, with possible deleterious effects on cardiac output, in a heart with a limited myocardial reserve and that carries a higher risk of fatal outcomes in special populations, such as patients with congenital or acquired heart disease. We present here a review of the literature, with the aim of achieving a timely recognition and management of neonatal supraventricular tachyarrhythmias, based on the diagnostic and therapeutic options available to date.
Las taquiarritmias supraventriculares del período neonatal son alteraciones del ritmo cardíaco que producen un incremento anormal de la frecuencia cardíaca del recién nacido, con posibles efectos deletéreos en el gasto cardíaco, en un corazón con una reserva miocárdica limitada y que supone mayor riesgo de desenlaces letales en poblaciones especiales, como los pacientes con cardiopatías congénitas o adquiridas. Se presenta aquí una revisión de las publicaciones médicas con el objetivo de reconocer y tratar de modo oportuno las taquiarritmias supraventriculares neonatales, con base en las opciones diagnósticas y terapéuticas disponibles hasta el momento.
