ANALYSES OF ELECTROCARDIOGRAPHIC INTERVALS IN CHILDREN WITH CHRONIC RENAL FAILURE

Abstract
Cardiac deaths account for a large percentage of the mortality encountered in children with renal failure and post renal transplantation. Within this category, a significant proportion of deaths are attributed to cardiac dysrhythmias leading to sudden death. The adult nephrology literature clearly demonstrates a higher prevalence of QTc prolongation and increased QTc dispersion in the renal failure population, compared to healthy controls. Data in children are much more limited. The purpose of this report is to critically review the pediatric and, where pertinent, the adult literature to determine the prevalence of various electrocardiographic interval abnormalities in patients with renal failure, those on dialysis, and those who have received renal transplants. The association of these electrocardiographic abnormalities with demographic and other variables will be discussed, as will the clinical implications of these abnormalities. Lastly, based on the data reviewed, recommendations on cardiac monitoring in this population will be provided.

Key words
Enfermedad renal terminal, electrocardiograma, arritmias, intervalo QTc
