Wolff Parkinson White Syndrome occurs due to the presence of accessory pathways that abnormally communicate the atria with the ventricles. It is one of the main causes of paroxysmal supraventricular tachycardia in young people and adolescents, in whom the ideal management is catheter ablation. This syndrome can also occur in younger patients such as neonates and infants, where the therapeutic options are different. We present the case of a 47-day-old patient who was admitted to a public pediatric hospital in Peru due to vomiting. Upon admission, she showed a heart rate of 250 beats per minute; wide QRS complex tachycardia was documented; later, on the electrocardiogram in sinus rhythm, signs of pre-excitation were evident.

OBJETIVO: Determinar la variación circadiana del inicio del infarto de miocardio, así como la población en riesgo en nuestro medio. DISEÑO: Se incluyeron los pacientes con infarto de miocardio admitidos a la Unidad de Cuidados Intensivos Coronarios del Hospital Alberto Sabogal del IPSS, desde enero de 1985 a febrero de 1991. Metodología retrospectiva desde enero 85 a febrero 90, y metodología prospectiva desde marzo 1990 a febrero 1991. RESULTADOS: De 103 pacientes estudiados, se determinó que el factor de riesgo más importante asociado fue Hipertensión arterial y Tabaquismo. Así mismo se determinó que entre las 00 y las 12 hs se presentaron el mayor número de infartos de miocardio. CONCLUSIONES: En nuestra serie estudiada, Hipertensión arterial y Tabaquismo constituyen los factores de riesgo más importante, y las horas de la mañana, es el momento en que se presenta con ma...
