[Diagnostic of the heart tumors in newborn and children (author's transl)]. / Diagnóstico de los tumores cardíacos en el recién nacido y lactante

Heart tumors in children are rare. Though of benign pathology they are clinically malignant and should be diagnosed early and promptly treated by surgery in spite of the poor results usually obtained. Any heart enlargement in the absence of congenital heart disease accompanied by rhythm and conduction troubles must be considered as suspect. Five cases of heart tumor are reported and clinically described. Four occurred in newborns and the remaining one before the age of one. Heart enlargement was a constant finding. The ECG findings were: W.P.W. syndrome, intraventricular conduction troubles and ventricular tachycardia, wandering pacemaker (one case each) and ventricular hypertrophy with surprisingly low voltages in the corresponding chest leads (two cases).

[Congenital heart block and pacemaker implantation (author's transl)]. / Bloqueo cardíaco congénito con implantación de marcapaso

A six years old boy was sent to our service due to a loss of conscience spell. He had no preceding history E.K.G. showed a complete A-V block. Laboratory findings were within normal limits. Cardiac catheterism was performed and it ruled out any antomic abnormality, making evident a good contraction ability. To decide pacemaker implantation we evaluted: 1. That cardiac frequency was not increased by exercise neither by action of pharmacologyc agents (atropine, insoproterenol).-2. The existence of wide and bizarre QRS ocmplex.-3. And dizziness spels. The patient has been controlled during the past two years. Parasistolia has appeared, not showing modification till today.
