title: Relationship between plasmatic concentrations of K, Na and Ca, and ECG from foals during postnatal phase.
abstract: The correlations between different electrocardiographic variables and plasma concentrations of K, Na and Ca ions were studied in foals of 1 to 14 days of age. The results obtained are only significant in neonate individuals of 1 day of age. Whilst the PQ segment and R wave duration showed a positive linear correlation (p less than or equal to 0.05) with plasma concentrations of Na and Ca ions respectively, the amplitude of the T wave showed a negative linear correlation (p less than or equal to 0.05) with the K ion. Moreover, the variability in duration of the QT and ST intervals can be explained by both Na (p less than or equal to 0.01 and p less than or equal to 0.05, respectively) and K (p less than or equal to 0.05 and p less than or equal to 0.01, respectively) plasma concentrations with which they show a positive linear correlation.
