ABSTRACT

Background: Cardiovascular Disorders are now the leading cause of morbidity and mortality in patients with Chronic Renal Failure. We performed a retrospective, cross and comparative study between EKG changes and their relationship with serum electrolytes and creatinine levels in 75 patients on CAPD in the hospital HGZ 194, for August 2010 from June 2011. Getting sodium, potassium, chloride and creatinine levels and electrocardiogram of 12 leads. The results analyzed with SPSS, and STATA, using Variance Correlation Logistics and χ². Results: The main change is the electrocardiographic left ventricular hypertrophy, with 30.67% in both sexes. For each unit increase in potassium in mmol/L 0.0077 seconds increases the P wave, p ‹0.05 CI (0.005 to 0.10). For each unit increase in chlorine mmol / l, P wave decreases 0.0003 seconds, p ‹0.05 CI(-0.0006 to -0.00000062). For every increase in creatinine, decreases P wave units 0.002 seconds, p ‹0.05 CI (-0.003 to -0.001). For each one unit increase Potassium in mmol/L increase in 0.014 seconds PR, p ‹0.05 CI (0.008-.024). For each increase in creatinine, increased QT interval 0.053 seconds, p value ‹0.01 and CI (0.01 to 0.09). Increases in creatinine and electrolytes are compared to levels considered normal for adults. We conclude that: The main changes are shown due to potassium, creatinine is an elongation factor of QT interval, and the discovery of chlorine and their participation in the P wave.
